OK guys, Just want to let you know that this post is not being ignored. I recognize there is an issue (seeing it myself) and I am currently investigating whether it is a problem with the software, a problem with a plugin or just a new implementation method.
In the interim, if you get the no new message since last visit, click on the all unread message link. Worse case, I can change the [New Posts] link to the all unread link and the post since last visit are listed first.
