I think something got messed up in the latest version? If I'm on away (blue balloon) and I get a message, the balloon turns green until I check the message. It also wiggles, which looks really weird and glitchy. I preferred the original way.

Too bad Adium can't use the Occupied and Away images. :( As marforic said, it would be great if Invisible and Message Received icons were introduced instead of the unfortunately useless Away/Occupied icons?
