Re: CPU utilization?
I have an early MBP w/X1600 graphics card, 2G ram.
I suspect I know what the issue is - the main screen has a constantly scrolling background. The tools screen lies on top of it, but does not completely cover it. It's probably a lot of work figuring out the details of the scrolling, first calculating the little window positions so you don't overwrite the tools window.
