Make this work for $10?

I’ve put a simplified fla together, if anyone could make it work the way it should can make $10. I would like to keep it using Tweener and AS2.

SWF is here:

FLA is here:

Upon opening the swf:

  • If you resize the window, it will continue to tile.
  • If you drag the image it will change colour, but tile will be cut and stop tiling (after there’s about two tiles margin).
  • After drag, if you resize the window colour will reset (seems to happen when window size is bigger than stage).
  • Press the white button top left to reset position to zero and reset colour.

All I want it to do is that it continues to tile even after colour change and window resized, and need the colour change not reset when window is bigger than stage. also tile seems to be in the + only and not in the - of the top left registration point, could that be done too?
thanks.
