Microwave oven (if it is close enough) or other devices that emit RF (which includes your computer and monitor). If your mouse has a receiver that is moveable, you might try moving it. Just a few inches can make all the difference. If it is built-in to your computer, then you obviously can't do anything about that other than move the computer itself. Kamm
