mouse pointer shift

[Russell Neches <russell@ccs.neu.edu>]

Hey there --

Another funky question for the group (sorry folks!). I've noticed that
occasionally the mouse pointer gets shifted 10 or 20 pixels to the
right of the mouse focus, and that the problem refuses to go away
until the system is rebooted. Google turned up a few hits on the X
mailing list with exactly the same problem on the same hardware.

I don't see any solutions posted. Any idea what causes the problem?
