[MlMt] 2-panel interface?

[Dave Carpenter]

How do I get back the ability to pull up from the bottom of the window 
in which I’m composing a message in order to see the “real” format 
view? Until recently there was alway a margin at the bottom where a dot 
was always located that I could grab and drag up. No more. And I looked 
through the menus for the multiple-pane options… I must be missing 
something.

Thanks,
Dave
