attahced to a button i am trying to make a seperate .swf file load into an instance on the stage, replacing the exisitng one, however, it seems that the new .swf file is loading but behind the one that is already there.

I have tried putting an unloadMovie action before the laodmovie on the button but that doesnt seem to work either?

any suggestions, the file is here - the button the script is attached to is the 'About Us' button,
