At random intervals, for 2-3 seconds, it stops working. A beep comes from my tower, and it kicks back in. So it's on it's last legs. Need a new one, but I can't get the the G5 anymore as it's out of date. Any advice on a mouse preferably with 7 buttons? Less/more buttons I'm open to. I guess the G9, but I've yet to go looking at any reviews. Would rather go with the Tech Support Forum here, as it has yet to steer me wrong.
