I wish I had an answer, but so far all anyone can say is they've never seen this problem before and scratch their head (figuratively). The best guess is that it relates to the cookies the forum software uses to identify you and that somehow the server isn't handling them correctly, but to date we cannot figure out what it's doing wrong. This stuff is really so far beyond my minimal computer knowledge that I can only depend upon others to troubleshoot it. All I can do is assure you that we are still working on it and want to solve it as bad as you do.
