Ok, this has happened before and then magically "went away", now it's back.
I clear my browser cache (including off-line), clear cookies, clear history AND clear Java (SUN, BTW).
(ref. this post: Clear Cache First Sticky)
I open my browser (IE6SP1), go to address "wxw.msfn.org" (the "x" is to prevent URL insertion), click on Logon button, enter my userid/password, and the screen repeats! The crazy thing is that I am logged on!
I can then go to eg. "My Controls", then to the bottom and click button "forums" and I'm right where I should have been (used to be) after initial logon...
What is up with that Logon? Again, symptom happened before, went away, and now is back. Heck, I even go to ALL doc/settings user-ids manually delete AND in the Windows folder... nothing anywhere!!!
