>Another thing, even when all forums in the upper frame are colapsed on refesh, a message still been displayed in the lower frame. The lower frame should be empty because ther're no message titles are displayed in such case in the upper frame.

Ok, I have added some logic for that particular situation as well.

Basically, if all your forums are collapsed, nothing will appear. Assuming you would have three forums, where the first two would be collapsed, the first message of the 3rd forum would then appear. Basically, the first message which is expanded should now appear.
