For quite some time I have seen a strange bug where emacs (running
under X11) would occasionally stop responding to keyboard and mouse
events.  The editor is still alive, and will change the cursor block
in response to focus events, but mouse clicks and keystrokes have no
effect.  The only way I've found to recover is to kill the emacs
process and start over.

Today I figured out how to reproduce it: move the pointer to the
menubar at the top of the window, then move the scroll wheel for a
click or two.  Works every time.  Does not appear to be dependent on
major mode.

This happens with stock emacs as shipped by Fedora and my own pretest
builds too.

In GNU Emacs 23.0.60.1 (x86_64-unknown-linux-gnu, GTK+ Version 2.12.0)
of 2007-12-15 on vena

I can't reproduce this on 23.0.60.50 (i686-pc-linux-gnu, GTK+ Version
2.12.9).

Can anyone on the list reproduce this problem?

Yes and no.  Emacs appears "hung", but clicking on a menu releases it.
I assume that moving the scroll wheel "activate" the menus, and Emacs
is just waiting for further instructions.  Changing focus to another
window seems to work as well.  I'm using:

23.0.60.1 (i686-redhat-linux-gnu, GTK+ Version 2.12.8)
