Just a thought, but I see Spybot Search & Destroy in your sig. Are you running the TeaTimer? Maybe there is a conflict. I see a few people complaining about high CPU but I have never had the problem. I would have to guess a conflict with another application. I never run multiple real time scanners. Just a thought that may be worth trying if you have the time. Or the dump would be helpful, they seem to be good about fixing such things. I'd offer to do it, but since I'm not having the problem I can't help them fix it.
