CPU usage in minimized Virtual PC?

I'm more familiar with VMWare Workstation. When I minimize a Workstation guest (XP Pro SP1 and also XP Pro SP 2 and Ubuntu) the CPU usage on the host is 10% or less for VMWare when the machine is idle. Is Virtual PC considerably different in this respect or is my problem occurring because I have Vista Ultimate on Virtual PC? When I minimize the Vista guest and the host machine is idle, my CPU is STILL used 25-50% all the time by the Vista guest on Virtual PC. Why? I leave the Workstation guests running for days, or weeks, and there is no undue usage of the host's CPU if the machines are minimized. I would expect the same from Virtual PC but my only experience with it is this Vista Ultimate machine. So, is this happening because Vista is such a pig? Why such high utilization of the host's CPU when the guest Vista is not being used but is minimized and the host computer is idle?

You can change the background behavior of VMs in VPC, on the VPC List

Thank you! I didn't have "pause Virtual Machine when inactive window"
checked. Hopefully, that will fix it. I have Indexing turned off so it
wasn't doing that in the background.
