What happens if you select "Ignore this exception location" in the Exceptions tool
and continue debugging?  Does it work?

It may be that this is a real error that is somehow masked / swallowed normally --
that seems somewhat likely since the app is exiting anyway when you close the last
window and thus this may not normally be noticed.

You can remove the ignored exception entry again if needed using the Clear Ignored
Exceptions item in the Debug menu.

If this doesn't help, please let me know and we can try to take a closer look at
