I have a minor issue I'm trying to figure out here; frequently message board topics that I have not kept current on (un-read, or partially read) will show up as having no new posts, when I can clearly see that the most recent post (as listed on the right) is one that I haven't yet seen. Why is this happening? It's kind of annoying, and makes it very difficult to keep track of read vs unread threads/comments.

It happens a lot, usually once a week at least. Is there anyone who can help me out here?
