After trying to customize my icons with LiteIcon and CandyBar and everything, my dock refuses to show up, at all. When I go to Finder and then to Dock, it has the beach ball. When I try to go to the Applications folder, it has the beach ball. I've tried Terminal "killall Dock" but it doesn't appear to be a Dock problem, but rather an Application problem. Maybe even both. This is my first week using a mac, I don't know what to do. I'm currently repairing disk permissions? Help please.
