Mine wasn't working for about 2 - 3 weeks, then last week it just started working again.

While it wasn't working, I was using the "View the most recent posts on the forum" towards the bottom of the Home page to find the posts I hadn't read yet.
I am using view most recent posts too but when there is an overflow of too many posts I often loose the posts without reading
IE7 never worked on unread messages
I am now gradually switching over to firefox but the problem is my Norton password security only works on IE and I am not ready to trust my bank logins to Firefox yet ( my subscription renewal is for 30 days and Norton got a complete new setup that is supposed to support Firefox
