Mouse jumping around

[Kevin Clark <kclark0153 surfree com>]

Not sure if this is a gnome problem but it seemed to happen after 
upgrading to 1.4.  Every once in awhile my mouse will go nuts and do 
loops and head to the bottom righthand corner of my screen.  I double 
checked my mouse settings in X and nothing has changed.  Any ideas?
I using a microsoft optical mouse with Red Hat 7.1 Gnome 1.4.

Thanks
