I tried searching and didn't find any similar thread, although I think I remember reading one about this a while back. Sorry if this is a repeat... My cursor just suddenly jolts to a screen corner and will not release until I pick the mouse up and set it back down, then it works for a minute and does it again. I've tried slowing the tracking speed down, but it still happens... Has anyone found a fix for this? P.S. I have a Mighty Mouse, but this happens with any mouse I use..
