Workaround to lack of modality when quitting in OSX

[Barry Levine]

In earlier posts, I described a bug (filed at bugzilla) that would 
permit an OSX app to be quit (using the Quit item from the OSX app 
menu) while in the middle of a modal dialog. I narrowed down the bug to 
the OSX Rev engine. If you compile in Windows (-for- OSX), the bug 
isn't present. Glad I kept my SBE subscription!

BTW - The shutDownRequest (and the apple event associated with it) is 
not sent when quitting the app in OSX using the Quit menu item. This is 
present no matter whether compiling in OSX or Windows. That bug report 
has also been filed. In the meantime, remember that any data you wish 
to have saved had better -be- saved before your user selects Quit!
