In random games this isn't working, ever since the interface change. In-game messages come and go, but clicking on the Message Log sometimes just goes into waiting mode forever. It's definitely not every game, and I can't figure out what the difference is.
This may have some connection with the problem where an illegal move (with associated message) causes strange things to happen when the submit button is pressed. I'll take note of the game number when this happens and test out my theory.
