So I got my friend a Macally Qball with their patented glitter ball technology crap, and we are both dissapointed so far. It seems that if you spin the glitterball too fast, the pointer goes haywire on the screen. Its as if the optical tracking cannot track the glitterball if it is moved too fast. This blows for a trackball. So, does anybody with the qball, or a similar expierence have any solutions/comments?
