- Is it the mouse pointer that's floating or the mouse itself?
- Windows doesn't have tabs. Some programs do. What program are you talking about that freezes when the mouse starts floating?

About every 15 min, my mouse starts floating all over the screen by itself.
Then it freezes up all your tabs
then give up and reboot
