Every so often in Mail, new messages will show up as empty: "This message has no content". In fact they're not empty, but it seems their processing was interrupted... and I can't figure out how to get Mail to take another look.
So, the question: Is there any way to refresh such messages without quitting and restarting Mail? That seems to work, but it is a pain when I'm in the middle of a lot of stuff.
I'm on Mountain Lion, with Mail 6.6 and an IMAP server.
