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.
