Let me know if it fails again. There is another option but it's not the nicest. It means you will have to logon each time you visit the site. I hope we don't have to go down that path.

The 'Show unread posts since last visit' link is not working properly for me, I have missed a lot of new posts in various sections on the forum even though the Unread posts link is showing no new messages. I am using IE6 at work and IE7 at home and it is failing on both. I have to go through each section to locate the new posts 

I have also noticed that some of the Unread posts are disappearing from the list after I have viewed a single post. For example, if I click the Unread posts link to see the message list, I might see 10 new messages. If I select one of the messages, then click the Unread posts link again, the list will now show 8 new messages instead of 9. Is this a bug in IE or with the link itself?  #$#
