Opening the Chatbox no longer disables the Recent Chatbox Messages window. Instead, the Recent Chatbox Messages window is disabled as long as the Chatbox is open; once your Chatbox session expires, the Recent Chatbox Messages window will reappear on the next page load.

Also, I'm working out a technology in my head that will allow you to open the chatbox in the same window/tab as you're browsing in. I'm not sure if I can make it work, or how well it will work, ATM.

On the Recent Threads display in the chatbox, you can now clear the list and only threads with new posts since the last time you cleared it (during the session) will appear; this makes it easier to "bookmark" your spot.
