I'm updating a course from a previous developer who is no longer here, and, of course, the code is not commented and difficult to follow, but, there's a "shell" that loads an "interface" file which has the navigation controls which load other movie files using addChild. The calls look like (slide is the variable with the swf name):

Actionscript Code:
iFace.screen.back.addChild(slide);


One of the loaded files is a "home" file, which has several interactive areas within it.
The problem is that, if the user goes into the home file, selects an area, then hits the "menu" button on the interface, selects the home file again, it shows up with the area that the user selected previously still displayed. If they select another section and then go back to home, the file gets reset.
Any idea how I can "reset" the loaded file?
I tried putting the following on the menu button after the function call:
Actionscript Code:
iFace.screen.back.gotoAndPlay(1);
but no luck.
Thanks!!
