Some of you using Mac OS X in combination with Firefox 3.0 Release Candidate 1 might have had problems submitting messages to the chat rooms. We are investigating why this combination of browser and OS does not respond to the enter key in our chat application. Firefox 3 RC1 on Windows is not affected, nor is any other browsers we have tried.
If you are affected by this, try using your mouse and click the newly added "send" button on the righthand side of the comment line instead.
