Logic Pro 9 CPU Usage issues?


I'm not in the studio tonight, but have my macbook pro with me, nothing external is attached to it. Normally I have an extensive amount of USB and Firewire attached...

I've cleared out all the caches

I've temporarily removed all the AU's

I've uninstalled the Euphonix MC Control drivers

For some unknown reason. The Activity monitor is saying Logic is using 100% of the CPU, though in Logic the CPU meter isn't showing any usage at all. I've never seen this before but it's irritating. Anyone have any ideas what is going on? I ran the Bonjour update earlier tonight, not sure if that has anything to do with this or not.
