This isn't a big deal, because there is a workaround, but often when I try to reply to someone, when I hit submit it comes up with a "Message text missing" error and the message box is blank.  I hit the "back" button, then submit again and it works.  ??

Edited to correct the error message after receiving it again tonight.

I posted the same problem and others have the same problem. Apparently this isn't a big deal or no one cares.
