Loading external swf completely overtop

hi there… does anyone know how to load an external swf overtop a current mc?

so far wat i have is a current mc… that has a button directed to load another swf into a blank mc i called “container”…

however… when it loads into the container… the mc underneath it is still there and when i highlight certain areas… i can still overlap certain buttons from the previous mc… anyway to load the external swf on top of the old one… without having the old mc’s buttons interfere?

the code i used was…

on (release) {
_parent.gotoandstop(“container”);
_parent.container.loadmovie(“porcelain.swf”, “container”);
_parent.container._x = -450;
_parent.container._y = -200 ;
}
