What kind of mouse? You may need to reinstall a driver following upgrading
to SP1.

My mouse randomly jumps to one of the 4 screen corners. It began after
this
week's Vista update. System Restore didn't fix it. I changed the "jump
to"
setting in the control panel and it didn't fix it. There doesn't seem to
be
any information in the knowledge base.

Does anyone have any suggestions?
