Has anyone else noticed that threads are getting marked as read without reading them? I use the "Unread Content" button (which is only at the top now and used to have buttons at top and bottom, but I digress) and I'll have a list of a bunch of threads, but after reading a thread that bunch will be greatly reduced. For example, early there were a whole bunch of unread threads stretching across the whole page (at least 10 probably more), but after reading one of the threads only 4 unread threads remained.
