After starting Open Office, the X cursor can no longer be moved off the left
edge of Screen 0 onto the right edge of Screen 1.  Instead, the cursor wraps to
the right edge of Screen 0.  It seems that there may be a way to "fix" the
behavior without restarting X, but I only stumbled upon it once.  Killing Open
Office doesn't fix it, and changing virtual desktops with the mouse or keyboard
doesn't fix it.  I'm not sure if this is an xorg-x11 / xinerama bug, an
openoffice.org bug, a metacity bug, or something else.

Version-Release number of selected component (if applicable):
6.8.2-37

How reproducible:
Sometimes.  I haven't narrowed down the exact steps, but it seems to happen when
starting oocalc from the command line, only sometimes, and may have something to
do with the window being placed on the opposite display from where the mouse
cursor is currently.

Steps to Reproduce:
1. Set up dual displays in Xinerama mode.
2. Open a terminal window on Screen 0.
3. run "oocalc" such that metacity places the window on Screen 1, e.g. first
fill up the empty space on Screen 0 with other windows.
  
Actual results:

Open Office Calc starts up on Screen 1, and immediately the X cursor becomes
confined to Screen 0.  Moving the cursor across the left edge of Screen 0 just
causes the cursor to warp or wrap to the right edge of the same screen.

Expected results:

The mouse cursor should not become confined.  The full use of both screens in
Xinerama mode should be retained regardless of what applications are started.

Additional info:

FC4, GNOME desktop, fairly standard settings (except focus follows mouse /
Select windows when the mouse moves over them), Clearlooks/Clearlooks theme,
metacity window manager.  OSS radeon driver, ATI Radeon X300 PCI-Express card,
dual DVI outputs connected to Dell 2001FP monitors.

Component versions:

xorg-x11-6.8.2-37
metacity-2.10.0-2.fc4
gnome-panel-2.10.1-10.2
openoffice.org-core-1.9.117-3.1.0.fc4

BTW, something I did just "fixed" the cursor.
