Cutting off access to the Stage?

i have a swf which will be loading outside swfs (not of my making). i realize there are potential security flaws… but neglecting the important stuff for a moment…

if the loaded swf tries to change the stage orientation… for example if i initially set my stage to align as such:

Stage.align = "TL";

and then the loaded swf sets it to be:

Stage.align = "CC";

this completely messes up the orientation of my swf.

this problem could be manifest in many ways, but my specific goal here is to be able to load Google videos without them messing up my swf. Is there any way to cut off access to the Stage object?

pace, thnx
