Ok, i figured out what is going on ...in your case the map is not moving around, only the plane simbol, that causes the confusion. What you are doing is correct, but for some reason the map movement is not visible (but it is taken in consideration by the system). When you see the symbol moving around, the map is "moving" also, its just not visible. When you declick the DATA, the waypoint jumps, because the map together with the plane simbol recenters,as it should. Not sure if its clear, but that is your issue: the map is not moving on the screen. Find the reason for that...maybe try a repair. Good luck
