In Win7, make sure you are using the legacy 1394 Firewire driver and have installed SP1

I notice that the CPU load seemed quite a bit higher so I took a closer look at what was happening. I saw that the CPU load on one of the four cores was swinging from 20 to 80% with Flex-5000 turned on but no applications running. The other 3 cores showed zero load. If I turn the Flex off or unplug the Firewire plug the CPU load goes to zero. I rebooted into XP and found that the same kind of thing happens but the load on the one core goes to about 16% when the Flex is on so I never noticed that it was happening. I am continuing to use Windows 7 and the radio works fine but this load for no good reason is bugging me. Any ideas what is going on?
