I've noticed the "new posts in thread" icon doesn't always clear after I've posted in a thread. Example: I post, and then come back through the "new posts" search to see what I may have missed. There's the thread I just posted to a few screen shanges before, with my name as last poster, but still showing as unread. Odd. I assume the server indicates which icon a user's browser should display for a given thread, and the icons themselves are stored in the user's browser. Am I right?
