Not.
I just bought the logitech mx500 after reading dozens of reviews that said how wonderful it was, and that the only thing bad was one of the buttons in a bad place...then wtf is happening to mine? For no reason out of the blue the mouse cursor will suddenly change direction and go off on some random path for no reason at while I am using it, this is especially anoyying in games, as it totally fucks up whatever I am doing to the max.
Do any of you know how to solve this problem? Or if this is even a problem at all? or do optical mice just suck in general? This is was supposed to be awesome..but I find my old mouse with a ball looking pretty good after this bullshit. Someone help
