Hey everyone, I just need some help with my iMac. I've only had it for a few months and this problem has surfaced in the last three weeks or so. Whenever waking the iMac from sleep, the mouse has tremendous lag. I can barely make it to system preferences and set tracking to the loosest possible, just to restart the machine. After a reboot it works fine until it goes to sleep again. Whenever I boot the machine to XP on the iMac, I notice that the mouse feels sticky and doesn't move as fast as it should. *I have tried a few mice, so I think the problem is with the iMac itself. On a few occassions, the right hand speaker stops working as well, in addition to the mouse problem. Does anyone have any ideas?
