Hi;
Hey Don; I so far haven't had the problem you speak of. It seems though if you are using a remote Wireless mouse it happens. My mouse caused that a lot. Then I got a Mouse-Pad. Haven't had any problems since!
I learned the Porsche 911 mouses like to go places when you are not paying attention to them. YES! the wheels on mine actually roll, Can you believe that? I was certainly surprised when I noticed that!
