This is very frustrating. On several occasions I've used this function because somehow toggling between the layout and the model spaces some of the line work has been pushed to the back or some of the aerial photography I'm using is brought forward.
So I try to use the Draw Order function to bring the that linework forward or on top and the random aerial photography to the back.
This sometimes causes items I've not selected to drop to the back or front. Even when I then try to redraw or regenerate the drawing it makes it worse.
