Resizing a Movie Clip to the Stage Size

programming flash
1

Hi,

I have an MC which is sized as follows:

contentbox_mc._x = 318.1;
contentbox_mc._y = 238.1;
contentbox_mc._width = Stage.width/0.3;
contentbox_mc._yscale = contentbox_mc._xscale;

This is fine until the stage size is altered…as the MC stays the same size unless the page is reloaded.

How can I set the size of the MC so it resizes as the stage size is altered?

Any suggestions would be gratefully received.
Thanks
