OK, this is getting silly. By the time I finish writing a 2-paragraph response, the website has timed out and I have to wander around for a bit before it remembers who I am. Normally it boots me to the store and loses my post. I've gotten into the habit of selecting the full text of anything I'm about to post before I hit "submit" so that once I get back to the "reply" or "post new topic" page, I can just paste the text back in and hopefully beat the timeout.
In case it helps: Win2K Pro, Firefox.
We'll take a look and see if we can replicate the problem.
