>The new messages at the top as well as the showing of the messages that are replies to me on the left will work some times and not others. For instance right now, it appears to be working. The new messages number is updating as it should. Other times during the day I will notice that it hasn't changed in the last 30 minutes to an hour (or more) and when I click on it, all of a sudden the number will jump up to the number of messages posted since I last clicked on it and all the replies to my messages will suddenly appear on the left.

I second this. Exact same behavior. I was just too lazy to start a thread on it.
