I just pushed out a couple alpha builds with preliminary Cataclysm fixes. The minimap button is not functional right now, but the basic application appears to be working. /vanaskos to bring up the main menu if you're using these builds. As always, grab the latest and greatest alpha for testing purposes and report any problems you find.
Edit: You'll find me on Raelea/Lanien/Egwenez/Mandraz (Alliance) or Traellina (Horde) on Gilneas(Beta) if you have questions and see me online.
