So between 2 successive reloads of the BBS's "Last 24 hours" page, 90 seconds apart, with a stable static IP address, I just got logged out.

It happens to me occasionally. A search of the BBS itself proves I'm not searching for the right thing. It's not a big deal, but I'm curious why it happens...

Does it happen almost exactly once a month?
I saw this for the first time yesterday. I was logged in when I refreshed the main index sometime during the morning (GMT) yesterday, but when I refreshed the list again in the early evening, I was logged out.

Might be a bug with the cookies implementation - you could keep an eye on the expiry date/time (Tools->Cookie Manager->Manage Cookies in Netscape 7) but it could be a server-side problem.

I've seen this happen on more than one occasion. There have been times when I've had a window in one of the forums open, and as I'm clicking through the topics (I usually open them in new windows), I'll suddenly not be logged in anymore, even though I *am* logged in in the other window.
