If you restart your browser, load chat.html, and then reload chat.html again, does it work
for you?

We've been working on a patch for a bug which might be causing what you've reported.  The
initial GET (to start polling) and the POST which adds your subscription to the chat topic
can end up in different sessions.  The solution we're working on is to delay subscribing to
topics until after the first poll returns (using a very short timeout, so it doesn't take
too long).

If that's also the problem you're seeing, a reload should fix things since then the GET &
POST are both using the same session.
