yeah, i asked my friend about it and he said i just needed a mouse pad, which i don't have. i've just been using it on my computer desk. ahahahah but thank you both! (:
I posted a similar question not too long ago. You mentioned that you use the mouse directly on the desktop. Bingo. For some reason, the lamination on the top of most desk surfaces reflects the laser back causing optical feedback. The quickest way I've found to stop the "tilt-a-whirl" is to move my mouse in a clockwise circle a few times. Moving it counterclockwise doesn't seem to correct it. That may help you, I dunno. Perhaps your mouse freaks out in a different manner than mine does. The idea of using a mouse pad is a bad one... to me, at least. The area of a mousepad is not quite big enough for me, I prefer to have the whole desk to work with. I use the arrow keys for movement, which is more comfortable for my left hand AND it allows me to slide the keyboard to the left more giving me even MORE room on the desktop to move the mouse.
