I have this weird problem on my mac mail. I think it was caused by accidently dragging and dropping something, but I don't know how to undo it. I'm attached a screen shot that shows how my inbox has 3 more inboxes inside of it! I don't know of any problems its causing but its kind of annoying! How would I get rid of them? And btw trying to just highlight them and delete them works temporarily, then when I write/receive a new email, they all come back!
