Okay, I'm trying to get through the most basic part of the Flash 8 tutorial, and I'm stuck on an impossibly basic task - I created a new flash document - drew a rectangle on the stage. That worked. Then I try to draw a circle over the square - done. Select it, and delete to cutout the circle from the square, but the square remains unaffected. If I double click on the circle, the square greys out, and again, deleting it has no effect on the square. What have I set improperly?
