Sorry Greg, but I doubt that's it.... Many people I know leave their machines on 24 hours a day (at home). I've had mine "on" for nearly 4 years now with the only mouse failure being when the little rollers inside the mouse got dirty. I cleaned them up and used a mouse-pad after that and haven't had a problem in the last 3 years...
