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.

In GNU Emacs 24.2.50.4 (i386-apple-darwin10.8.0, NS apple-appkit-1038.36)
