Unloaded?

It may seem like a stupid question…
When a new movie (swf) is loaded into a movieclip, using _root.movieclip.loadMovie(main.swf) for example, is the previous one then automatically unloaded? Or is it still there, but just hidden behind main.swf?

Thankx!

yea it stays there behind the movie you are loading
[AS]
on(release){
unloadMovieNum(1);
}
[/AS]

yes you can make a button and put the script that Digitalosophy gave !and it will load the previous mc !
