Re: Difference between "html" and "htmlText" in clipboardData?

Interestingly, it shows a key for "html" but not "htmlText".

Do you know what the difference between those keys is?

Is this just a bug in the Dictionary and there is no "htmlText", with
the "html" key using LC's htmlText?


They appear to be synonyms; at least, I get the same results with both keys.

Re: Help: Does anyone use legacy message box behavior?

Hi Folks

I’m in the midst of making the message box redirect work in all
engines (https://github.com/livecode/livecode/pull/5156
) and it would seem
that there’s a legacy message box behavior that could be removed from
the engine. It’s not used by the IDE. The behavior is if no message
box redirect is set then it looks for a stack named “Message Box”,
sets the text of the first field then raises the stack. As this is
only an IDE thing I strongly suspect we are ok to remove the code but
while I’m waiting for the team to wake up in Scotland I thought I’d
check here!

It would be easy to work around even if you have been depending on it
because it’s just setting the property and then handling msgChanged
to put msg where ever you want.


Do whatever it takes, I've been waiting for this for years. I could 
really use it right now. Debugging standalones is an exercise in 
frustration.

Nested groups

Because they effectively deepen the message path, I'd wager there is
some difference, at least in terms of initializing the message path as
the objects are unpacked before preOpenCard.

That said, given the speed of the natural message path I'd wager it
would be small enough to be unnoticeable, and perhaps even difficult to
measure.



I was thinking about the amount of redrawing the engine would need to do 
to render them.

I have a number of stack with a lot of controls in multiple nested
groups. For me, the groups are primarily for organizing objects on the
card so I can find what I am looking for as a developer. OR when I want
to move a set of related control around. In all such cases, I have never
noticed a visible difference in rendering of the cards vs card with few
groups or fewer controls in a similar number of groups.

This is just human perception. I have never timed renderings to compare.


Thanks. I'm working with a stack that has some memory issues which 
includes many image-rich nested groups. I don't think this is 
contributing directly to the problem but wondered if reducing the number 
of groups might help.

Script locals in library stack script

[J. Landman Gay via use-livecode]

I have a splash stack that opens a data stack from a server. The data 
stack has a substack which is used as a library with "start using".


The handlers in the library work okay. Some of them store data in script 
local variables in the library script. The script locals do not retain 
their values, they are almost always empty when the library tries to 
access them later.


Is this something others have seen? LC 8.1.3 rc 1.

I’m guessing you don’t mean in a separate request on the server. I’m
not aware of anything special about the way server does stuff with
variables so someone would need to chase this down based on a bug
report I think.


Right, after downloading the data stack, for this stuff it's all local 
messaging. I'll try to track it down before submitting a bug, I just 
wondered if this was a known thing. I'm seeing other problems that 
indicate the message path isn't what I expect.

Hi Jacque,

This is valid JSON (and also valid ASCII).  In JSON, any character in a
string may be encoded in the form \u where  is the 4-digit
hexadecimal representation of a Unicode codepoint.  No textDecode()
operation is required.

JSONImport() handles this correctly.

1) Create a stack with a field and a button
2) Put the text above into the field
3) Set the script of the button to:


local tJson
put JSONImport(field 1) into tJson
answer tJson["UserName"]


4) Enter browse mode and click the button

You will get an answer dialog displaying "Eduardo Bañuls".


Thank you, and Trevor also, for this. I hadn't heard of importJSON() 
before but it seems to be what I need. I'll take Trevor's advice and 
textDecode the JSON before running it through JSONImport(). All the 
incoming data is being decoded already anyway so I'll just leave that in 
place.

My question is, what do other people do about this? If you generate a

One of my clients said she'd had it with Windows installers and now 
ships the product as a zip file. The user is instructed to move the app 
folder out of the zip folder. This is just about the only hitch in the 
process, because Windows presents the zip folder as a regular folder and 
users think they can just double-click the app inside the zip archive.


Other than instructing naive Windows users to drag the app folder out of 
the zip archive, there have been virtually no other issues. The signed 
app itself works fine without interference from the OS.


Windows users have become used to installers and expect them, but if 
your app is self-contained and doesn't require changing registry keys or 
other OS-level stuff, it works pretty well. I know that's not what you 
asked, but that's how we solved it.

Re: How to lose your work in a couple of clicks (dirty flag)

I have been poking around in the IDE stacks and found this. I think it's a bug 
but wanted to run it up the ol' flag pole with the list first before I submit a 
bug report.

Recipe:
1) Open a stack.
2) Make a small change.
3) Build a standalone.
4) When presented with the "Save/Cancel/Don’t save" dialog, click on the "Don't 
save" option.
5) Exit the IDE and you will not get the options to save your stack because the "Don’t 
save" option clears the "Dirty" flag.
6) Re-open the stack in the IDE and observe that your change(s) are not there.

Expected result: User should be present with the option to save the stack when 
exiting the IDE.
Observed result: The user is not asked to save the stack when exiting the IDE.

When the "Cancel" option is selected the "dirty flag is not cleared as I would expect but 
"Don't save" clears it. I think this is wrong. Even if you don't choose to save at that moment The IDE 
should leave the stack marked as "dirty". I could see someone inadvertently losing a lot of work.


This is documented briefly in the dictionary under "savingStandalone". 
When a standalone is made, the stack is closed and removed from memory. 
After it's built, it is re-opened. If you don't save beforehand, changes 
are lost. I think that's just how it has to be.

It is part of the OS and so overlays the stack. You can hide or show it,

Is there a way to ensure that the "back button" on any device's web

This has to do with the default behavior of LC and the OS it runs on. By 
default, LC mobile apps quit when they are not frontmost. The behavior 
after that depends on the OS.


On Android, the LC app will remain in RAM until the OS needs the memory, 
at which point it will quit. If the user goes back to the LC app before 
it has been removed from memory, the user will return to the place it 
last left off. If the app has been removed, it re-launches to its 
opening screen.


On iOS the app is not retained in RAM, it always quits. Ralph provided 
the work-around that allows the app to run in the background. It is not 
supported and can fail depending on what the app does. If you use it, 
test to make sure it works reliably.

When you are working on a server, you can only see what gets put into 
the browser. There is no stack to examine visually. Anywhere a script 
uses "put" without a destination, the text will go to the browser window 
where you can see it. Anything that is put into the stack itself won't 
be visible.


Each time the server runs a script, it starts from scratch. Nothing is 
saved from previous runs (unless you script it.) So you can't run the 
script on the server and then look at the stack later -- it won't have 
been saved.


Another option if you do want to see a real stack inside a browser is 
the (as yet immature) HTML5 feature. That does put a stack into a 
browser window, with buttons, fields, and all the basic object behaviors 
you are used to. It is still young yet though and has some limitations.

set the menubar of stack st to stMen

This causes a X-style menu to appear in the stack window, not what I was
aiming for . . .

According to the dictionary, this should simply set the menu, not override.


If the menu should be available to all stacks (on OS X) then you should 
set the defaultMenubar.


If the menu should only be available to a single stack, set the menubar 
as you are doing now, and set the editMenus of the stack to false. This 
will cause the stack to truncate slightly as it scrolls up to hide the 
menu group.


An alternate approach is to simply set the menubar of the stack to a 
hidden menu group. That way no scrolling occurs.

Is this a bug?


I don't think so, you need to get the selectedObjects and run a loop. I 
think that's how the property inspector does it too. In fact, if this is 
just for development, it's easier to do it in the PI.

Search the LC Lessons. I found a swipe example here:

There are also some lessons on 2-finger swipes in there somewhere. A

can just get it from the debugger. This is amazing.


I'd suggest that documentation make it clear what permissions and 
inclusions need to be set up. I'm not sure I'd make the permission 
automatic, since the final standalone may not want that permission set 
and the developer will probably forget to unset it, especially if they 
didn't know it was turned on in the first place.

Set a field to use locktext, traversalOn, and autohilite. You can select

It may be the difference in the character sets for each platform. If you 
always develop on a Mac, use macToISO() on the character when the 
platform is win32. LC usually does the conversion by itself, but if you 
are populating the list from a custom property, the script has to do it.


If you aren't using a custom property then I'm not sure why it isn't 
translating. Is the list coming from somewhere outside LC? If so, 
textDecode() should work.

Re: Script locals in library stack script

[J. Landman Gay via use-livecode]

On 2/10/17 5:56 AM, Bob Hall via use-livecode wrote:

I’ve been wondering this myself. I’m going to try to create a recipe
but it looks like the TTL of script local variables is different than
what I thought I knew it to be. I “think” I started see this behavior
about 8.1.0-ish timeframe but not sure.

In the past few months I started to put everything into properties as
I found that my understanding of how script local variables behaved
was different then how they do.


I have set the LC preference to preserve variables. In the past I have 
rarely seen a script local lose its value, and never if there has been 
no script compile. I don't know exactly when it started but I was in 
8.1.3 rc 1 when I noticed it. I spent two days trying to fix the 
problem, eventually gave up and worked around it. The extremely odd 
thing was that the script had three script locals, and only one of them 
lost its value. The other two were fine. It was impossible to track down.


Here is what I was doing:

Stack Main has a substack "InternetLib" that contains all handlers that 
deal with server connections. It is put in use when Main opens. 
InternetLib handles server queries and returns the retrieved data. That 
all works fine. It also has a "setter" handler that can be used to store 
data in a script local variable in its own script, and a "getter" 
handler to return data from the script local.


What happened:

1. Stack Main calls InternetLib to do a query.
2. Stack Main manipulates the returned data, parses out what it needs, 
and calls the "setter" handler to store it in the script local "sVarA" 
in InternetLib.
3. Immediately after the handler ends, Stack Main calls InternetLib to 
do a second query.
4. Stack Main uses the returned data and calls the "setter" handler to 
store the value in InternetLib script local "sVarB".

5. Later, stack Main tries to retrieve a value from sVarA. sVarA is empty.
6. Retrieving data from sVarB is always available.

The third script local, sVarC, always retains its value. It is not 
involved with the above process, it is set earlier when Main is opened.


When tracing through the handlers, it appears that sVarA loses its value 
some time between the first query and the second. What I need to do is 
find a way to track sVarA to see when it changes. There used to be a way 
to do that but I can't remember how, or else I forgot it on purpose 
because it didn't work.

Re: "Deleting" Stacks in Memory - What About Behaviors?

[J. Landman Gay via use-livecode]

How would the engine know whether that behavior is used elsewhere, or will 
be needed in the stack that opens next? The easiest way to get the behavior 
you want, without any scripting, is to put the script in a button in the 
stack. Then when the stack is deleted, the behavior is gone.


If you're using script only stacks, it's not difficult to remove the script 
stack when you no longer need it.

But if we delete a stack that has behaviors set from external 
*_behavior.livecodescript  stacks for controls in the "main" (parent?) 
stack, those behaviors are still in memory.


Does it make sense to file an enhancement request, to at least allow the 
dev to set a preference

Re: Script locals in library stack script

[J. Landman Gay via use-livecode]

I know, that's why I didn't report it. I scoured the script looking for 
a difference but I couldn't find anything, the two queries were executed 
by the same handler. I looked for anything that would empty the variable 
and that wasn't there either.


My current theory is creeping stack corruption. The stack ran with only 
this one oddity, but when I tried to reload it from disk later it was 
reported as corrupted and wouldn't open. I had to open it in BBEdit and 
use a days-old backup in LC to paste in all the changes. Apparently it 
had corrupted several days before, but because I'd left the Mac on with 
the stack open I didn't know.


I've sent the working stack and the corrupted one to bugzilla though I 
don't know if the team can make anything of it. The missing variable 
appeared in LC 8.1.2 so I switched over to LC 9 to see if that helped. 
That's when the stack gave up. I think I'll stay away from 9 until it's 
out of dp, but there's something going on with LC 8 too in some unique 
circumstance. I haven't had any trouble with 8 before now.

If only one script local is getting reset, then it cannot be that LC is 
resetting script locals because they would ALL reset, not just one.

It may be possible to set a breakpoint on the script local to trigger when it 
becomes empty.

Re: automating enabling of plugin settings on new versions

[J. Landman Gay via use-livecode]

Instructions are in the bug report, but basically you make a copy of the 
plugin, do whatever you want with it, and put it in your user extensions 
folder. It will override the LC copy.


If you've installed for "this user" then that's who it will apply to. If 
you installed for everyone I assume the change will apply to all users. I 
always install for just me so that's what I'm familiar with.


If LC updates their plugin then you'd have to replace your copy, but as 
they promised me in the report, they'll tell us if that happens.

Memory leak?

[J. Landman Gay via use-livecode]

I've been watching Activity Monitor on OS X while LC 8.1.2 is running. 
On launch it registered about 52 MB of memory. I opened a stack that has 
no background scripts running, it's completely inert, and after a while 
it jumped to 84 MB memory. I let the computer sleep and left it on all 
night. When I woke up the Mac today it was still at 84 MB. I worked in 
some other apps but never brought LC to the front. After about 30 
minutes it's jumped to 134.7 MB.


The reason I started watching this is because someone else asked me 
about random crashes and his Activity Monitor registered an increase of 
about 10 MB every few minutes.


Does anyone else see this?

Thanks Bob. That´s what i am doing right now.

As i cannot guarantee that my customer won´t use such filenames, i will

Right. You can make any changes you want, but you can't save them to disk.


This fairly torpedoes my whole portability concept where I go to a
substack of a mainstack and perform some actions, finally setting
some properties of the mainstack. In retrospect now, I can see why
seasoned livecoders don't go in much for the concept of substacks.
However convenient it is to have a single stack file with all the
substacks included, it appears I can no longer do this.


I don't think any of us avoid substacks, I use them all the time in apps 
for resource storage or as libraries. The trick is not to include any 
substacks that need write permissions as part of your standalone. Save 
the substacks out as independent stacks, and add them to the Copy Files 
pane in standalone settings. Those will become independent mainstacks 
and will be writeable (provided you copy them to a writeable location on 
disk first.)


I don't think you'll need to change your scripts much. You could even 
create a different splash stack, save that as the standalone, and have 
it open your original splash stack which is now its own mainstack, just 
as it is in the IDE.

Did you mean "checked"? If checked, that option will extract substacks 
and save them as independent mainstacks. If not checked, they remain 
substacks. If LC isn't behaving that way it's a bug.


In either case, you can't write to the app bundle. If you want to save 
data, you need to copy the stacks to a writable location on first 
launch. The standalone builder can't know where you will want to save 
those stacks, and always places them into a folder you can access with 
specialFolderPath("resources").

Don't forget to use "OMG/LOL/derisno/perv" as in for example: "OMG, why
are you using 6.7, are you a total perv? Derisno past! LOL." :)

There is a history to every product, and not only do we learn a lot by
comparing past to present, but the latest version of LC that people take
for granted owes a lot of fixes and some features to Paul in particular due
to his meticulous work and testing, providing a huge benefit to the entire
community!

It's wonderful to keep up with recent LC releases, especially where Apple
is concerned, but sometimes circumstances and LC bugs/features can affect
the speed of that process. Then you have people who grab the latest DP,
precisely because it is the very latest thing, and get confused trying to
tell the difference between their own bugs and DP bugs. I help people with
that often enough to know that a chorus of "just grab the latest" is advice
that needs clarification.

Paul:
> We are seeing a weird menu rendering issues under OSX

I believe this menu issue is also a current bug in LC 8.1.2! Haven't
tried it yet in LC 9, but I will soon. LC 6.6 was okay, so it must have
been introduced in 6.7 and remained until now.

Change for the sake of change keeps some people incredibly happy, others
less so! The new interface does take some getting used to, and the old
interface definitely had its strengths too, as I've realized lately with
certain particular tasks and with teaching others. Much to learn from
comparing and critiquing LC versions, enjoying the very latest as well as
some past specimens!

Re: LC Server & Server Based Stack?

My site is focused on old-style CGI. It's an alternative to LC server 
scripts, which act more like PHP,. Both are viable methods but slightly 
different.

No, though the person who asked me about it uses players. I opened an 
additional small stack with a simple button script in it, clicked the 
button, and the memory went to 153 MB. It had stuck at 134.7 for a 
couple of hours until I did that. I'm pretty sure the difference is the

the size didn't decrease. Seems like it should have.


This could all be normal. I never really paid attention before.

Re: where does the standalonebuilder saves the substacks in an Mac OS App?

[J. Landman Gay via use-livecode]

I think that's right, Apple enforces this rule.

The standalone builder will move files to a Resources folder when it 
builds the app. For backward compatibility, scripts that reference the 
engine folder are redirected to the Resources folder automatically.

to work, no application is allowed to write or modify anything in the
old location where the actual application binary resides, but in the
new location they can.

As an administrative user I am able to copy files to both locations,
but sandboxing is not about folder permissions. It's about executable
permissions and it's baked into the OS so no one can (ostensibly)
change it.

That is my understanding at least. I've not dug in enough to know for

The first thing to try would be replacing "exit to top" with "pass 
dragdrop". If you don't pass the command, the drop doesn't happen.


Everything below is off the top of my head, untested, but here are some 
general ideas.


If "pass" doesn't work, try:

on dragDrop
  put the dragData ["text"] into tText
  set the dragData ["text"] to cleanASCII(tText, cModeList, cCustomChars)
  pass dragDrop
end dragDrop

And if that doesn't work, try:

on dragDrop
  put the dragData ["text"] into tText
  send "cleanUp tText" to me in 0
  pass dragDrop
end dragDrop

on cleanUp pText
  put cleanASCII(me, cModeList, cCustomChars) into me

Try the "send" method then, which updates the text after the drop.

Apparently the problem is intermittent. But it also looks like exit

Re: DragDrop makes windows unresponsive OS X

The theory is that something is interfering with the drop, so altering 
the text after the drop completes might fix it. Could be a bug, but 
using "send" may work around it.


On 3/24/17 4:38 PM, Bob Sneidar via use-livecode wrote:

In that case sending would only replace the dropped text. No point in
that. The text is getting into the field using either method. It's
just that the window controls become unresponsive like they might if

Re: Object Selection Handles

[J. Landman Gay via use-livecode]

Just a general agreement here, I also have some issues with the new 
design for selections. The circular handles look strange to me but it's 
an adjustment I can deal with. The dotted outline bothers me more 
because it is harder to see the edges of the object, though I suspect it 
was implemented to match the Project Browser.


The main problem I have with it though is that I can't easily apply and 
observe effects applied to the edges of objects. To see a small shadow, 
for example, I have to de-select the object first. Then if it doesn't 
look right, I have to re-select the object and also re-select both the 
effects pane and the shadow dialog in the inspector, because the 
inspector resets when nothing is selected. That makes adjustments a 
painful process that has to be repeated many times before I get what I'm 
aiming for. That, for me, is the main irritation.

I suspect that Craig didn't know that stacks can be menus. I can't think

Was it something I said?


More like something you did. :) I think you put the engine into a loop. 
Back in the old MetaCard days, when I was just a tot and walked to 
school uphill both ways (in a blizzard,) this used to be the only way we 
could make menus. It's still the only way to build a menu that has real 
icons or other non-text elements.


In the menu stack, you put buttons that do stuff, usually in mouseDown 
or mouseUp handlers. Size the stack to about the width of a real system 
menu and make it just enclose its contents. The buttons should be 
edge-to-edge in a vertical column, no borders. Basically you are 
implementing a hand-made menu object. When the user clicks on the 
buttons in the stack, they do menu-like things, like calling a handler 
in the mainstack or whatever. (Your test stack doesn't need any button 
handlers if you're just testing the display.)


Now you need a way to to tell LC to display the stack menu, so you 
create a new button on the mainstack. That's the one that needs the 
menuName, so it knows which stack to draw. When the user clicks this 
mainstack button, it looks up its menuName, finds that stack, and 
displays it.


I wonder what the engine was thinking as it tried to menu-ify a stack 
that was holding the button in the stack that was calling itself to show 
the stack that was holding the button in the stack that was calling 
itself to...


Never mind. You'd think there'd be a recursion warning though.

Translating escape sequences

[J. Landman Gay via use-livecode]

I'm dealing with non-English languages, and JSON data retrieved from a 
database comes in with unicode escape sequences like this: Eduardo 
Ba\u00f1uls.


I need to translate those. I can do it by replacing the "\u" with "0x" 
and then using numToCodepoint() to get the UTF16 character. But there 
could be many of these in the same string, so I'm looking for a one-shot 
command that might just do them all. I don't think we have one.


The alternative is to loop through all the text, getting an offset for 
each "\u" and then calculating the number of characters after that to 
use with numToCodepoint(). But will it always be 4 characters in any 
language?


Or is there an easier way?

Of course the chances of encountering whacky characters like that is
small, but you'll have to make sure you
can cope with them should they crop up.

If you look at Eduardo Ba\u00f1uls you will have to strip what comes
after the '\' of the prefix 'u'
and the suffix 'uls' and then you can cope with whatever is left:

Reasonably pseudo-code following:

set the item delimiter to \
put what's after the item delimiter into HOLDER
delete char 1 of HOLDER
delete the last char of HOLDER
delete the last char of HOLDER
delete the last char of HOLDER
put "0x" & HOLDER into NUNUM

at this point "NUNUM" could be alost any length, but that should not
matter unduly.

Re: Changing a group visible boundaries by script

Try setting the group's boundingRect to the rect of the control, then 
setting the rect of the group.

Hello,

there have been several solutions for password fields around the community
(Eric Chatonet, .), but all I have seen so far are not complete (e.g. no
copy/paste) or safe in handling or not fully handling all chars. The most
comprehensive solution I have seen is based on the input of "rawKeyDown the
Key" getting the chars, replacing them by asterisk or bullets and storing
the clear password in a custom property. But that solution has a pitfall, it
doesn't works with non standard ASCII characters, like German umlaute,
because  you can't  retrieve the original char from numToChar(theKey) for
theses non standard ASCII chars.

Before inventing the wheel again, I wanted to ask, if anybody has a
sophisticated piece of code for handling a password field willing to share?
"Ask password" is not a solution for my case because the password field is
part of a form.



Thanks

Tiemo

Re: Translating escape sequence

[J. Landman Gay via use-livecode]

Thanks. I actually was using jsonImport() with these strings 
successfully (no wrapper required) but it has a bug on Android that 
makes it unuseable. That's what caused the problem in the first place, 
because jsonToArray() doesn't deal with escape sequences.


So I went ahead and wrote a decoder for escaped sequences that works, 
but found out I still can't use it. If I replace the escapes before 
using jsonToArray(), jsonToArray throws an error; it can't deal with the 
UTF16 strings. And I can't run my decoder through the keys of the 
converted array after jsonToArray is finished, because they are already 
munged into garbage characters by then.


So I'm stuck, I don't see any way to deal with these. I'll put in a bug 
report about jsonImport() but it will probably be a while before it gets 
fixed.


I hope someone else has an idea.

JSONImport does it.
If the escaped string is not in JSON format this function will wrap it in JSON 
then let JSONImport do its thing.

put deEscape("Eduardo Ba\u00f1uls")

function deEscape pEscapedText
put "{'1':'**dummy**'}" into temp
replace "**dummy**" with pEscapedText in temp
replace "'" with quote in temp
put JSONImport(temp)into pArray
return pArray[1]
end deEscape

Roundabout but does the trick.

Of course the chances of encountering whacky characters like that is
small, but you'll have to make sure you
can cope with them should they crop up.

If you look at Eduardo Ba\u00f1uls you will have to strip what comes
after the '\' of the prefix 'u'
and the suffix 'uls' and then you can cope with whatever is left:

Reasonably pseudo-code following:

set the item delimiter to \
put what's after the item delimiter into HOLDER
delete char 1 of HOLDER
delete the last char of HOLDER
delete the last char of HOLDER
delete the last char of HOLDER
put "0x" & HOLDER into NUNUM

at this point "NUNUM" could be alost any length, but that should not
matter unduly.

The alternative is to loop through all the text, getting an offset for

use with numToCodepoint(). But will it always be 4 characters in any
language?

Or is there an easier way?

Alas, no. I did something similar earlier this evening. If you replace 
the escaped sequences before running it through jsonToArray, the 
function throws [an error and gives] up. If you run jsonToArray first, 
there are no escapes to process, they are all converted to garbage by then.


But Monte has a fix in the pipes. I think he's been lurking here and 
fixing bugs before I can report them. He just wants us to think he's 
psychic.


I beat him to the bug in jsonImport though.

Yes, Apple required that change a while ago.


And if this is correct, how do i open them? At the moment my button
script (go stack …) , which works for Windows does not open the
substacks in MacOS X. If i move the substacks manually to
'test.app/Contents/MacOS/' then of course my scripts can open them
w/o modification.


Apple doesn't want anything in the folder except the executable now. The 
best way to handle the files is to use specialFolderPath("resources") as 
the directory. That will alway point to the correct location on any OS. 
On Mac, it specifies the Resources folder (and is a synonym for the 
engine folder for legacy stacks.) So your path should be:


 specialFolderPath("resources") & "/stackname.livecode"

It will work on Windows too.

Re: this stack gets every closeStack message

Place a breakpoint in the closeStack handler. When it fires and the 
script goes into debug mode, look at the popdown menu button just to the 
right of the debugging icons at the top left of the script window. 
That's the execution contexts, and it tells you what path the message 
took. The top line of the button list is the handler with the 
breakpoint. Choosing each line in order underneath will trace the path 
the message took before it reached your stack's breakpoint.

I just added dp6 to the firewall manually. My guess is that the Mac 
reads the name of the app and determines it's a "new" app but when the 
firewall actually checks for it, it sees dp 6 as an update rather than a 
different app and doesn't update its acceptance list. That's purely a 
guess though. It still doesn't explain why the automatic acceptance of 
signed apps doesn't allow the connection by default.
