Hi, My mouse is getting kinda jerky and doesn't want to hit the spot I want it to go! I realize that this usually indicates some gunk inside... But, I just cleaned it about a month ago!! Same symptoms, and there was hardly any gunk in it at all, then. (I can get it apart, but have to wait for husband to come in, so he can put it back together! i can't do it.) Could anything else be causing this extremely annoying behavior? Have I got a bad mouse? It seems to get this way, really often... Grrrr! Thanks, NancyT
