I'm using Snow Leopard on a year-old MacBookPro. I keep all my programs rountinely updated. I've searched Help, the Apple site, and this site's archives without success.
I want to mark an item in junk mail as non-junk. I can't click the non-junk button because it isn't there. In other words, the button at the top of the junk mail list stays as "Junk". Trying Messages>Mark doesn't work either: there is no choice for "not junk", the only choice is "Junk". How can I fix this?
