does your mouse pointer and stuff ever spazz like crazy if your stylus/pen isn't near the tablet?
cause mine does that sometimes for some reason
That usually only happens when I leave the stylus on the tablet then try to move the mouse. If you're not using the tablet and can easily unplug it I'd do that.
Ah, that's a problem. What tablet is it?
Hm...I have a few friends with it and they've yet to have problems with it. Have you tried re-installing the driver?
