Tonight I was restarting my MBP to shake the dust out of an unusually long run and all was well until I went for the dock, which I keep hidden until I need it. It is suddenly off to the right side of the screen as you can see here. I tried restarting again, moving it to the sides of the screen and back, killing it, everything I can think of but nothing works. Has this ever happened to anyone? Any help would be greatly appreciated.
