The Cookie Cutter effect usually works fine for me and I am able to Layer pictures like one picture ontop of the other or have 2 pictures appear on the screen at once. But for some reason, when I put one picture ontop of another one, underneath the one ontop is just black - the other picture won't appear underneath. I've never had this problem before - I don't know what happened. It won't let both the pictures show up at once. Please help!
