Somehow I've gotten my claws-mail install into a strange state where the "execute immediately" setting not longer seems to apply to moves.  The move completes in that the email message dragged from my local mail folder into an IMAP account appears in the new account, but it is not removed from the summary view of my inbox.

The new copy of the "moved" message is just fine.  Text on the line in the summary view is shown in blue and a small blue-box arrow is shown in the check-mark-topped column.  Apparently claws-mail thinks the message is moved and not executed.  If I click on the blue line the message view shows the default "This message can't be displayed" error.  If I restart the application then I get the same behavior, but the line is no longer flagged in blue.  It seems like the cache of message headers is out of sync.  If I rebuild the folder tree for the local account the moved message is then removed from the summary view.  Any idea what I did or how to fix it once and for all?
