I have a Microsoft Intellimouse Explorer, an optical mouse. It has recently begun to play up; the light which indicates power turning off, rendering the mouse useless. This happens for about 8 seconds each time, then the mouse will stop working until the compuiter is rebooted. There doesn't seem to be anything of help in the help files. This is getting really frustrating, and seeing as in the mouse is only a month old, could spomeone help?
