You know, I must apologize to Mr. Obscenewish. I thought you guys meant that when you are logged on, statically, you lose connection to the RealJock website. Now I see you mean that occasionally when you go to a profile and try to come "Home" you are sent back to the original login prompt.
Yes, that's happened to me, very occasionally. It didn't seem remarkable enough to me, since I have the login information automatically saved, and all I have to do is click "login" without typing anything.
So, yes, I have had that problem too, with Deer Park (FireFox).
