<<Get an optical mouse, the kind without a ball. I promise you won't regret it. Make sure it has the same kind of plug as your does, some have both included, but I'm not sure all do.>> Everyone has different experiences. And in this case, I really had a lot of problems with my cordless optical mouse. I finally took it off and went back to my old one. The cordless was very difficult for me to control it, and your description of your problem sounds exactly like the problem I was having. Bettye
