Ok, I paid closer attention and I get the flashing in focus and in background. Got a couple good lockups when switching back to a client as well. Executing a macro from the razor interface would end the locking up, just like with smartcpu. Scatch the SmartCPU stuff. Reminds me more of when I used to run Razor w/o turning on XP Compatability, and w/o running as administrator which I'll test in a few minutes.
