Wow, how weird - now that you mention it, my PC did that today too, and the chances are good that I was on PT when it happened, since I'm on here a lot It hasn't done it yet during this session, though. The problem I have, which makes me nuts, is when I am on cheesy America Online and I navigate to a site that has sound on it, like a wav or midi file. As soon as I exit that type of site or try to navigate anywhere on it, I get booted off of AOL - it just vaporizes, and I'm staring at my desktop. Nobody at AOL or Microsoft has been able to explain this or help me. There is nothing that makes me crazier than trying to troubleshoot PC problems
