I am sorry if I have been unclear. Let me clarify. '[Y]ou're talking about the "Drag within/between groups using right mouse button" option': yes. '[A]ll other options work, but this option has no effect': yes. But - ah: I discover the real problem. The dragging is working; but there is no visual feedback, which, I submit, would throw anyone. Perhaps this video (on Box) which I have taken will help.
