If you're like me and have the swapMouseButtons perference unselected because you are on windows, then right-clicking on a morph and picking the 'select' menu item raises an exception because popUpFor:at:hand: is expecting a position for the at: argument, and currently this sends in a MouseEvent transformed by the relevant amount. We need to take one additional step and extract the position from this newly translated event, which I do in this change.
