A left press on the view cube held and dragged orbits the view: the press is not a click until it moves or is held past one, then the pointer grabs and the view orbits about its centre as the other orbits do (the move it took to tell a drag from a click turns the view too). A press that doesn't move is still a click on the face, edge or corner. While the cube is dragged its hover highlight is off, the release is not a click, and the navigation bar's orbit or pan tool doesn't also act on the drag. A press on a floating window over the cube is the window's and starts no orbit, as with the cube's hover. Tests: the s39 scenario drags 48 px right from FRONT and the view turns 22° without clicking the face
