Much relieved! Here's a summary of the recent fixes:
The locking up was at least in part due to a failure to release the queue
and let scripts continue. It was a simple one-line fix once I found it.
That was unrelated to the boolean business. I noticed it when I tried to
load a bogus structure -- $adfljdaf -- in the same script as had a
prompt() function, and JSmol just stopped in its tracks. I'm sure there
were other cases.
The infinite recursion problem was due to two things. There is a 1-ms
timeout that I was throwing in every 100 ms of script execution that
allowed the script processing to be interrupted and other threads to
proceed. But it turns out that there was some faulty logic, and in certain
cases the situation could arise where the command loop just cycled
infinitely.
The business with Boolean and Safari's magical (i.e. multithreaded)
behavior was a teachable moment about why you have to be very careful
modifying fundamental browser classes such as Boolean and Number. Tweaking
them is fine; replacing them with your own is not wise! I still have no
idea what was going on there, but anyone who redefines Boolean has no right
to complain, I think.
Minimization stopped after the last cycle of code compression that I
created, in which I found I could wrap all the methods with "anonymous
functions":
;(function(xx,yy,zz,....){
[all JSmol code here]
})(XX,YY,ZZ);
This allows the Google closure compiler to replace global variable names
such as Clazz.declareMethod with aliases such as "a" and reduce file size
by 30-40%. But to make it work, I had to have the automated build process
replace all "Clazz.xxxx" with "Clazz_xxx", and then I had to find all of
those. My code analysis using an Excel pivot table missed one that happens
to be only used in JVXL surface loading and minimization.
Robert Lancashire found a bug that made it necessary to have Info.j2sPath
== "j2s" and not any other. Now we should be good to go with any j2s path.
Mouse wheeling problems were due to not handling unexpected "left-drag"
notifications from a mouse during wheel motions. Who would have thunk it?
The popup menu/language switching problem was something simple, but I can't
remember.
Some of the Safari/Chrome local page problems were due to using the
<object> tag instead of the (deprecated???) <applet> tag in webkit
browsers. I guess we're back to <applet> now, even in HTML5.
And, I don't know if it's just me, but funny, I haven't seen a warning box
all week. Happy day!
