Comment 26 for bug 231034

I have the same problem:

  Ubuntu: 8.10
  Emacs: emacs22-gtk 22.2-0ubuntu2
  Metacity: 1:2.24.0-0ubuntu1
  Dual Monitors
  Assistive Technologies enabled

Symptoms:

  Cursor turns to window resize pointer and stays that way. Mouse will move around on the current screen but will not move to second screen and clicks do nothing. Switching to text terminal and back "fixes" the problem. Pressing Caps lock sometimes turns the direction of the resize pointer and eventually frees up the mouse.

Note also that the window does not actually resize until the mouse is released then it moves to wherever the mouse is at the time.

This happens at random but is pretty easy to reproduce by making attempts to resize gtk-emacs screen.

This may not be related but I also have a bug where gnome-panel crashes when I try to use a launch button on the second display. The gnome-panel used to lock up and use 100% CPU until I enabled assisitive technologies now it crashes and restarts instead. Since both problems involve metacity and assisitive technologies it could be related.
