My recently bought Logitech G5 'Gaming' mouse is no doubt a fantastic mouse. But everytime the CPU (Late 06 MBP) is doing something intensive, even if it's just one of the cores. When the mouse is moved, the pointer will skip to a random spot a few inches away on the screen. This happens over random intervals (from 2+ seconds). Sure it's not so bad when I'm firing up VMWare and it skips around because response time isn't vital. But i'm playing games with it, and well, in WoW that means you run off cliffs and miss the potion, and becomes a major PITA. I know the first version of the G5 (the rust coloured one) had similar problems. But apparently the new blue one (the one in question) is fine. The surface I'm using it on is a heavy sheet of cardboard (backside of a notebook). Anyone else have this problem? And what does logitech do in these cases? I rang up tech support and got hung up on. Or do I need to go to the guy I bought it from? EDIT: after running 'yes > /dev/null', it might not be totally CPU related, maybe the GPU has something to do with it. In any case, I'll be playing in another account to see if the problem arises there.
