Did you try your brother's laptop with your mouse pad in the place where you normally use your laptop? There's one other mechanism I can think of that can cause mouse jitter. Some optical mice can be sensitive to external light reflected by the mouse pad, typically from fluorescent lights. I used to see this with old Sun mice. You could try using a different mouse pad (e.g. dark neoprene) or changing the lighting to see if it makes a difference. But you definitely need to find out why your mouse is jittering and stop it. As Carlos said, it's using power every time it jitters. Cheers, Dave -- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
