Came in this morning and while checking some boxes remotely, noticed when I went back to my main machine, Prima was running on 1 core. Since it's an I7, I looked to see what else might be running. Only FreeHal and Wuprop. Thought maybe that Prima went the way of others and was using all 8 cores for 1 WU. Check a Dual core and it was running 2. Went back and checked preferences. Everything looked good. Ran CPU-Z and it said I had 1 core and 1 thread. Did a reboot and everything went back to normal running 8 Prima WU's. Not sure wtf was going on. Only thing I can think of was some relationship between what Yafu was using before it went back to Prima. Any thoughts? Don't want to see that again.
