I just recently upgraded to Mountain Lion and I'm loving it so far. However, before I installed Mtn Lion I had a custom dock installed. I used Mirage to make the dock invisible with only the icons remaining. I forgot to turn Mirage off before upgrading and now my dock is stuck with a bezel around it as if it was on the side of the screen. No matter what I do I can not put it back to a standard dock. Any suggestions?
