System Hang when Saving XISF

[sixburg]

This was originally connected to another similar thread. 

The issue:  Pixinsight hangs when saving files
How to replicate:  Open a file, save as .XISF, press enter before the next dialog appears
Result:  Pixinsight hangs (must Force Quit...changes lost)
How to avoid:  Wait for the dialog to fully display (but in the heat of the moment fingers often move more quickly)

Happens under MAC OSX El Capitan, PI  01.08.04.1195

I cannot reproduce this issue on the two iMac machines I have at hand now (one with OS X 10.10 and another one with 10.11, up-to-date), and I really use my fingers fast (the dialogs are not shown).

I have no idea why this happens on some machines. Sorry for the inconvenience. Try to cool down things a little when you save an image for now, and let's hope this gets fixed "automagically" when we release a new version next Fall.

Thanks, Juan.  I've slowed down for the most part ;-)  Sometimes I get going so fast and bang!!!  Clear skies.

i am seeing this as well, however, i just triggered it by accidentally specifying an invalid view name when trying to do ChannelCombination. had to force quit PI, opened the files again (maybe not necessary) and misspelled the name again. first two times the invalid filename dialog came up and i dismissed it with a click; the third time when i dismissed it with a click, the UI hung up. the console is stuck right before it would have printed "<* failed *>". it seems very repeatable.

when the UI is stuck, the backtrace of the main thread looks like this:

what's interesting is that if i then right-click on the PI icon in the dock and say "quit", the "are you sure" dialog comes up and dismissing it causes PI to "wake up" and resume accepting UI events. the console finally prints "<* failed *>" at that point.

hopefully this sheds some light on the problem?
