Subject: 24.2.50; OS X dialog box locks emacs
Date: Wed, 22 Aug 2012 15:11:22 +0200

Starting from emacs -Q, evaluating the following causes a dialog to
appear.  It is impossible to dismiss the dialog and impossible to
interact with the rest of emacs. 

(let ((last-nonmenu-event nil)
      (use-dialog-box t))
  (y-or-n-p "Cache preamble? "))

It should be noted that I found this when I clicked on the
preview-at-point toolbar button in AUCTeX, so artificially setting
last-nonmenu-event seems justifiable.

I can't reproduce this, either on 10.7 or 10.8.  I tried about 50 times...
Does it happen always?

Yes.  I'm on a fairly modified 10.6, so it may be that I have something strange on my system.

It doesn't really bother me, since I have set use-dialog-box to nil.  The bug that really bothers me is 12245. :-)


I have tried tracking it down a bit and it gets stuck in nsmenu.m line 1784:

ret = [NSApp runModalForWindow: self];

I can print out the value of self etc. if you think it would help.  But if nobody else can reproduce this perhaps it's better just to ignore it.

Apparently 10.6 (and earlier?) doesn't handle modal loops the same.  I have checked in a fix that works on 10.6 also.
