I'm not sure what you mean by "under power". I'm still getting used to the interface myself, when you hover over the bar anywhere where you can see the blue background, i get a 4-way arrow and am able to drag and click. If your custimisation isn't locked, I have no clue. I think there is also a lock on the small bar that has the icons on it to get to your gear, skills, etc. make sure the padlock icon on the top right of that is open too.
