Funny, I posted the same topic, but I know longer see it anywhere. I was talking about the "Razor" mouse that I had and issue's that it was causing. So I went back to my older "Logitech Mx 518) and everything works Great now. I was considering getting the G500s, but the reviews on it were very poor. So since my Three year old mouse is working very well, why should I up grade........

Those mx518's are tough little buggers.
