I don't believe that I have come across this problem before. Are there any specific pages where it happens? If you cannot log out and need to, deleting your IETLOGONSESSIONID cookie will force the ending of your log in. You would only remain logged in from day to day if you had chosen "Remember Me" when submitting your username and password.
If you have found threads of concern, please use the link below each message that allows you to report them to the moderators. As on many forums, the moderators are unable to review every message posted, and the assistance of users in identifying problem threads is very much appreciated. I agree about the value of the Mk1 human eye; it's just that we need more of them
