Flagged folder shows messages as unread and I'd like it to stop
It's cool that Mountain Lion brought a flagged folder to Mail. But I've obviously read the messages I've flagged and this folder shows every flagged message like it's new.
I try to keep my inbox near zero, so it's annoying to have a bunch of messages nagging at me as if they were unread. Does anyone know how I can get these messages to stop showing up as unread?
