I use an old blue Logitech Optical Wheelmouse at home and at work. I really like them, don't see the need for those cordless mouses. So I bought another two of them, as that would be handy at times. They were OEM versions, black this time.
The problem is that these mice don't work properly on my Mac. They jump back when I'm moving the mouse around (I move to the left and halfway they jump back several inches to the right), and if I don't use the mouse, I see the red light going on and off every ten seconds. This depends slightly on the position of the mouse on the desk. The result is that the monitor won't go to sleep. It seems that they are too sensitive or something. The old blue mouse works fine, no problems at all.
Anyone have the same problems? I'm thinking about returning them.
