Problems unloading movie - very urgent!

programming flash
1

Hi,

I use code
on (release) {
_parent.createEmptyMovieClip(“container”, 1);
_parent.container.loadMovie(“bwy.swf”);
_parent.container._x = -50;
_parent.container._y = -300;
}

to open a new window over a swf movie. Now i want to close this new window without opening the browser.
Can you help me with this code?

This is a flash presentation. It works in fullscreen.
Thanks
