Just sat browsing the net and I noticed the dock disappear off the side of the screen then reappear again (No I don't have auto show/hide enabled). I had a quick look in Console and the only entry relating to the Dock I can see at the time is:
Dec 4 16:49:59 Eds-MacBook-Pro com.apple.xpc.launchd[1] (com.apple.Dock.agent[250]): Service exited with abnormal code: 1
Can't see anything that should have caused the dock to quit so not sure if this just a glitch or indicative of anything more serious.
