I was wondering if anyone else has had this issue: A lot of times, I will start PF and things work well. However, after a few minutes, PF seems to lock up. I'll try to open a thread and nothing. Zip. Zilch. No matter what I do, all I get is that damned progress bar moving at a snail's pace and "waiting for physics forum..." Most times, the only thing I have been able to do is to restart either Firefox or IE (it happens on both for me) and wait a few minutes. It doesn't appear to be a traffic volume issue. Any ideas as to what this could be?
