I have the 30" display on my PowerMac G5 and this problems only happens on this screen. I would be happly playing WoW (world of warcraft) then for no reason what so ever my mouse pointer disapeers, gone *puff*. I will exit the game then the pointer would not be there, i will reconnect it and still nothing. Not untill i restart my G5 does it apper again. It does not bother me that much but sometimes and i am fight the last boss or i am doing something important i would hate for the mouse to *puff* away. Any help?
