Ok, I found a solution for my problem and I thought I should share it with
you,
in case someone runs into something similar in the future.
These are my findings:
1. Zinc seems to need a few Kbs in the local storage by default. Even if you
create the simplest app
with 1 line of code, e.g. mdm.Dialogs.prompt("test"); or even only
mdminit(), Zinc will have to access local storage.
Fortunately, it needs less than 10K of local storage, which seems to be
the size the flash player allows by default.
So, if you have a Zinc application that doesn't save files on the local
drive, the 10K limit is enough for you
and the Local Storage Dialogs does not popup.
2. The problem comes when the application needs to save more than 10K per
session. This means that
if you need to save a file larger than 10K the dialog will come up. Of
course, there is no way
to by-pass this thing if you really need to save more than 10K, since
it's a native flash player thing.
The only solution would actually be a workaround.
3. Zinc does not only save stuff to the hard drive when saving a file or a
folder, e.g. with mdm.FileSystem.saveFile()
but also when DECRYPTING a file or a string. In my case, that's what was
happening. My application didn't save files larger
than 10K, and those that it did save (3K, 2K, 8K etc) didn't cause any
issue.
But, the application descrypted several files, one of which was larger
than 10K (it was 50K). All others didn't cause
any issues, but this one was big and Zinc apparently needed disk space
to decrypt it, so it actually tried to save
data on the hard drive, which was more than 10Kb and this caused the
Local Storage dialog to come up,
asking for permission to save up to 100K to the local storage.
4. The solution that applied in my case was to divide that file into smaller
ones, each one less being than 10K.
Kind regards,
Dimitrios

Thanks eric,
Yes, they only see it for the first time.
As this is a downloadable app, it's not about a specific domain
but rather "Local".
The thing is in my case I don't deal with SharedObject at all.
I don't use SharedObjects in the whole project.
The issue arises because the app is trying to write to the hard drive,
using Zinc's mdm.FileSystem.saveFile() method.
The result is the same of course - the Settings window appears.
Nevertheless I've read again about SharedObject.
I don't think there is a way to stop this window from popping up,
flash player is too strict about security to allow me do this.
Right? If anyone has a solution or workaround it'll be great!
Dimitrios

You should read the documentation for localSharedObject - you'll find
many
interesting things. You'll be able to see what the viewer's setting
currently is, etc.
A user may get that dialog the 1st time data is saved for the domain -
and
then won't be seen again. I think that is the point of your initial post,
right?
I can't remember if comes up as a default the 1st time or not, but I
think
it does just for security reasons.

Hi Mike,
What do you mean I can query their setting?
