(Background -- I don't ever want to see a message pane!  It marks things read that I haven't read, and takes up room I can't spare)

When I open T-bird, the 3-pane has the message-pane open.  Press F8, nothing happens. Do: View ->Layout ->[x] MessagePane.  Sometimes!  I pretty much have to do it twice.

Go to another folder.  Message pane is open!  Go through the nonsense above.

Go back to Inbox.  Damned message pane is back!


Reproducible: Always

FOLLOW-UP after some additional testing.

The situation is even more annoying than I described above.

If I, say, 
(1) open the Inbox and eliminate the message pane, then
(2) open another folder IN A NEW TAB, and eliminate the damned message pane, then
(3) switch back to the Inbox tab.

The message pane is BACK!

Also, I need to do View ->Layout ->[x] MessagePane TWICE -- ALWAYS TWICE.
The first time, the selected message is displayed in the pane which was previously blank; only on the second time does the message pane disappear [for a little while].

A possibly related issue, which I will file as a separate bug, there is a regression in the way the list-of-folders is displayed in multi-tab.
