Quick question for clarification purposes. Do you have Firefox set to delete cookies on closing? Assuming you are also a FF user that is.
Tools Menu - Options - Privacy Tab
See what the "Keep Cookies Until" dropdown says.
Also, do you allow FF to remember your login details also? I did, and I don't know if that overrides the cookie setting. If I said no to FF remembering, would it override what I set on the ICB login form for example. Might call for a test.
