When foldit should be idle, consuming vast amounts of cpu time on Windows

I have several machines that I run foldit on, but I am particularly conscious of this on my 4-core laptop because the cpu fans sound like jet engines when running at high speed. The desktop machines have much quieter fans, but on my 2-core desktop I get the same effect.
I have monitored this with the Windows Performance Monitor (a tool you can find in the administrator's tools in the Windows control panel).
Environment: Windows 7, 64 bit operating system
I run foldit, and open a science puzzle. I am not running any of the tools, just viewing the protein in the Window. If foldit is minimized, the four processors are all running at 0 to 15% capacity. But if I maximize foldit, one of the processors is constantly running at about 80% to 90% capacity. Because it is using so much cpu time, it heats up and the cpu fan spins faster to cool it off. There must be some thread that runs when stuff is being displayed that is in a tight loop consuming cpu time.
One the two core desktop, one of the cores runs hot when foldit is maximized, but goes to almost 0 when minimized.
This is not a new bug. I have noticed this since I got this laptop last April, but it has risen to one of the top things I'd like you guys to fix after you get the stability problems done. Let me know if you need any more details on reproducing the bug.
