Back Button Problem !?!

I have just made a simple flash based website and decided/had to add a ‘back’ button to return to the home page where the menu is located.

But it just loads the home page within the old page. Which actionscript would i need to load home page again with out loading the Digital Llama (LINK HERE) again, as it has a popup and would be annoying if it had to popup each time u pressed back…?

i use this for all the buttons, so the ‘back’ just has main.swf as the link name…

on (release) {

any help would be appreciated.
