John,
It's happening to me both when I come to FT using the IP address of 64.78.185.85, and when I use
www.flyertalk.com.
Signed in earlier, with the "Remember Me" checked, yet after reading a few threads, I noticed that I was suddenly logged out. Had to sign in again to post this message in the thread. Just started happening over the last few days, and I haven't changed any settings nor the browser (Netscape 7.2) on my pc.
Seems to be happening to others here now too, so it's not my computer.
