Damn dock problem in 10.1, helppppppp


I just installed 10.1. Woohoo it seems great except I cant get my dock to become unstuck from the right side of the screen- it is 'pinned' to the right on the bottom of the screen and I can get it central. Now when using 10.0.4 I used a nifty little app docking manouvres to moce the dock around without typing code into terminal. This i am guessing may tbe the problem. as this app no longer works under 10.1.

Any ideas on what the terminal code may be? Or other ideas to get out of this? it is reallly bugging me. thanks.
