I sometimes place big backdrop objects around the frame to prevent the player to be able to see outside the frame window if they adjust the size of the window in flash. The problem if I do not place backdrop objects around the frame, the player can see objects that they are not supposed to see outside the frame. Placing these backdrop objects is a very clumsy but only way I can think of to solve this. Is there some faster/better way to do this then to place big backdrop objects all around the frame? It is especially clumsy when I have a big scrolling game. I have attached 2 images, the first is one with white borders around the frame so it hides the stuff around it if the player zooms out the window. In the second one you can see what happens without the borders.
