? ? The tooltip for the Refresh icon says "Refresh / Mark all threads as
? ? read".

? yep, but at least for me, it does not seem to Mark the threads as read -
? it marks them on the spot, but when I log off and log on again, they are
? again all marked as unread!
I've just had a go at marking them all as read, and then logged off and they are still marked as read. Could it be something to do with cookies?!
