white frame defining render area, gone

EdwardEdwardEdward

When setting up a render, I used to get a white frame surrounding the area to be rendered. The frame would differ in shape and size, depending on which option I chose in the render settings -- square, or academy flat, letter, legal, 16mm, etc. But since I've downloaded DS 4.5 onto a different computer, I no longer get any white frame showing me the area to be rendered. How can I get that white frame back?

Thank you very much for your help.
