When I hold both left and right mouse buttons down at the same time, the mouse shuts off after 20 seconds. I need to disable this because I play a game inwhich running involves holding both down. Has anyone had the same trouble for any other reason? I assume this is a feature inwhich may have a way to disable it. Might anyone have a solution? The HP sites have not helped and when I google it brings me to a Mighty Mouse page listing everytime. Thanks
