[MlMt] delete message in Inbox, jumps to previous

[Alain Israel]

As of today, for no obvious reason, when I delete a message in the Inbox 
window, the cursor moves to the previous (upstream; messages are sorted 
by date) message. Before it used to move to the next (downstream) 
message, and this is what still happens in the other mailboxes (although 
I did not check them all). Any reason why this has changed? More 
importantly, how to get back to the previous, more logical, behavior?
