Okay...  I have one example of a laptop that has had problems but is 
currently running Fedora-8: An IBM A31p Thinkpad.  I have two more of 
these laptops that had Fedora-8 installed on them that have now been 
reverted to Fedora-7 because of the Zoom problem.  The other systems 
currently running Fedora-8 are server systems that are not running X 
Windows.  There are some workstations in remote locations running 
either Fedora-8, Fedora-7 or some version of Ubuntu that are not aware 
of the problem or are not using the feature.

The Zoom feature tries to work with this laptop but fails to return to 
the original virtual desktop size and does not allow the mouse to push 
the borders of windows that are smaller than the virtual window.  X has 
to be restarted to restore the original largest desktop.

And since the /etc/X11/xorg.conf file I am using is small:

cat /etc/X11/xorg.conf
