The order of objects change in the simulation window
The ordering of the objects change as soon as an event is added to them. This happens in the simulation. Why? Can someone tell me hoe to avoid that? I have some circles in a vertical order which I can move up or down. Then on the top and bottom I have two black boxes. They are to mask the circles when I move the circles up or down, but when I go to simulation, the circles come forward again!
