Having problems running 0.6.4 on my system. I'll start the test, and most of the time my cores are barely being used (looking at a windows gadget showing me the 8 threads). One time I went into the settings, I think I just turned on the Everest monitoring and the sound option, and after that I was able to run a test of 20 passes ok. But I haven't been able to get it to work since. I've tried going into the settings and making some changes to see if that's what made it work the first time, but there wasn't a change.
