I have my prefs so that I automatically watch threads I post in now. What I noticed was when I replied to a thread, my reply was moved into the thread (like normal) so I have to assume in someway the page refreshed or reloaded a small part of it. I went to the top of the screen to click watch thread (forgetting my pref settings) and when I did it prompted me with un-watch this thread. I am wondering if this is the nature of how it is supposed to work and i'm supposed to refresh the pageor if this infact a bug. It's not really a big deal as it only happened because I made my first post in the thread as a reply with watch thread as a default action to posting but I assumed that because the post is added into the thread as soon as you post it right in front of your eye I assumed it would refresh the "watch" status as well.
