When I open message view, switch to another tab, then go back to the message tab, the body part of the screen isn't redrawn - what was there the moment ago (e.g. list, editor or even other mail) is still there.
Header, status and MIME chooser are shown, but not the body.
Also, when switching MIME type and then back to the previous one, the body also isn't refreshed.
