[AS3] Drawing API - Solid Overlap?!

I’m trying to simply draw a solid shape consisting of various other shapes, however, when I overlap two shapes, the overlapped area becomes transparent again. For instance:

            var myShape:Shape = new Shape();
                myShape.graphics.beginFill(0x000000);
                myShape.graphics.drawCircle(10, 10, 25);
                myShape.graphics.drawCircle(20, 10, 25);
                myShape.graphics.endFill();
                this.addChild(myShape);

The above code is AS3, but I believe the same thing happens for AS2 as well. The overlapping area between the two circles is not clack

Is there something I’m missing to make it one solid black object? I’ve seemed like I’ve crawled the livedocs for an hour!

Thanks!
