This might explain some of the wierd issues I've been seeing with
emails, but I generally tend to run VM inside emacs in a gnu screen
session, so I'm very text based.  And what happens is that sometimes
when I read a message, then move to the next message parts of the
screen aren't re-drawn properly, which is usually fixed with an C-l to
force a re-fresh.

This happens with both 8.2.0b (emacs 23.1.1 centos) and 8.1.2 (debian
squeeze emacs 23.2.1), though I suspect I run into this more often
with 8.1.2 just because I'm usually reading my home email that way.  

So I've recently tried moving over to TMUX instead of gnu screen, but
I still see the problem randomly.  If you can come up with a text
case, I'd be happy to test things out and let you now how it looks.
