[MlMt] next message is auto-marked read

[Shoshanna Green]

I'm setting up a new M1 iMac running Big Sur, whee! But MailMate is doing something odd that it doesn't do on my old High Sierra machine.

I use the two-panel layout, opening messages in a separate window. When I move or delete a message that is open in its own window, the message that is then newly selected in the messages list gets marked as read, even though it has never been opened. (This doesn't happen if I move or delete a message from the message list without opening it in its own window.) I'm sure I've seen this misbehavior before, but I can't remember what I did about it...help?

Thanks,
