Just had a strange problem with my mouse - it's a Habu laser mouse, and there's no light coming out of the laser on the bottom of it. I can't actually remember if there's meant to be or not, but I thought there was before. Anyway, it's behaving fairly normally (a bit sluggish maybe) in most directions but when I try to move it down-left, the pointer doesn't move very well (jumping around and not moving fast at all). Erm?
