>I understand that, but when I logged in at the time of my original message I could see new messages from people on my twit filter.

I think this might be related to a temporary patch I put a few days ago when the filtering was not applied when the treeview was turning dynamic. By that, I mean that when there are too many new messages, only the headers (forums and categories) are sent and then later, on request, the required messages from the selected category will be pulled out.
