BitmapData... weird

Hi there.
I hope someone will be able to answer me.
Could you check this swf or fla (those are sample to show you what’s weird)

What happen so. :h:

I’m drawing on a MC (line) a black line, 5px thick, using lineTo(0, 100);
I’m copying this image on the BitmapData object (myBMP.draw(line));
I’m clearing the MC (line).

I’m redrawing on the MC (line) a white line, 5px thick, using lineTo(0, 100);
I’m copying this image on the BitmapData object (myBMP.draw(line));
I’m clearing the MC (line).

the result?
I can still see the black line underneath. I mean just the border of it… How come ?

If you’re zooming and clicking several time on the draw second line you will see something more weird… Anyway for me…
Any help appreciated :slight_smile:
