Mouse acting crazy in Fedora

Okay, so I'm running Fedora, and sometimes (often) when I come out of a screensaver, the mouse completely freaks out... almost impossible to control, random clicks, and it keeps snapping to the bottom left corner. I figured it may have been something related to Fedora as it's a fresh install and, well, it's new, so... I popped in the RH 9 install disc, got to about the third screen, and let it sit for about an hour... when I came back I had about the same problem.

I also have XP installed on another HD on the same machine, never had any trouble with it.

I realize this probably isn't enough information, or even the right kind, but I'm new to Linux... tell me what you need to know and I'll tell you all I can.

Any help appreciated.

Your mouse is haunted by the evil spirit of the infamous pirate, wood legged fedora.

next time you come out of your screensaver, restart the X environment by pressing control+alt+backspace . that should bring you back to a login prompt.
restarting X might clear out any shennigans the screensaver envoked.

this wouldn't fix the cause of the problem, but may help the symptoms.

okay, that fixes it.... but wtf?

does this happen with any screensaver? or just a few of a particular type? i'm no guru, but maybe there's a plan b.

At the moment it's hooked up to a KVM, and it sometimes happens switching between boxes... sometimes. So, it's not just the screensaver... seems like an X deal, because the reset worked, but, why should the KVM have anything to do with X?
