I've been having problems with my wireless Mighty Mouse lately, seemed to start when I upgraded to 10.5.1. The mouse keeps randomly getting disconnected when I'm using it. Every few minutes/seconds, it's disabled and I get the "Connection Lost" message. It only lasts a second and I just click for it to work again, but when in heavy use this happens every few seconds and gets annoying as hell. Wireless keyboard's fine. Anybody know how to fix it?
