Starting just last night I'm finding that Mail on my Air is not managing to open, move, or delete some messages from my In Box. It seems to happen suddenly to a message that I've had no trouble with before. But then once it has been that message, it remains a problem. And the status message at the very bottom left just seems stuck on moving or downloading some (apparently random) number of messages. This has never been a problem until last night, but now it's sticking around. Opening/moving/deleting on other devices (another Mac, iPhone, webmail) is no problem. But it's not clear whether or not it clears up the problem on my Air.
