Macintosh

So everything has been fine the last few months then today suddenly after I log on and undock I get nothing. Just a big black screen of space. Right clicking does not bring up the menus or anything. The overview still works so I can dock back up, but when I do I no longer can see the station environment either. I reset the cache and all that jazz but don't feel like re-downloading the client today, and suggestions?

Edit: The Mac repair tool may have fixed it.
