Hi. This is gonna sound odd but every time I move my mouse real fast it goes out of control. If I don't move the mouse the cursor stays but with one little twitch and it is half-way across the screen again. This also tends to happen in Linux but Win2k is the worst. If I don't move it for about 3 seconds it goes back to normal until I move it fast again. And I am not even moving it that fast!!! Please help. Thank you.
