AH is SUPPOSED to use 100% of the CPU resources, thats why you arent supposed to have anything running in the background.
If you shut everything down thats visibly running on your desktop, hit ctrl/alt/del and look at your CPU resources, once you quit moving the mouse around your meter should drop down to 0%, and bounce between there and 2%. Any more than that, you have processes running in the background eating up CPU time. That can get you dumped out of AH or cause lockups.
Thats all. Carry on.
