Frozen while zoning

[DevGrousis]

Over the past week or so, every single time i zone, i am frozen seeing the last thing I saw as i hit the zone. No loading screen, or anything. It just sits there until I get tired of staring at it, at which point i force the application closed, and log back into my char, who is happily on the other side.

I am running a macbook pro with bootcamp.

Any ideas?
