How do I disable my main menu when loading an external swf?

Hi there,

I’m currently designing a new site in which, when a button on the main menu system (on the main timeline) is released, an external swf file is loaded. When this happens, I need the main menu to fade out and become disabled until the user is done with the external swf.

I’m happy with the fading out part and am using buttons within movieclips for each button in order to use the following action script:

on (release, releaseOutside) {
_root.container.loadMovie(“photomap_001.swf”)
_global.mediaAlphaVar = 0;
_global.agencyAlphaVar = 0;
_global.Menu_LineAlphaVar = 0;

}

But I was hoping somone out there might know another quick bit of actionscript to ensure that the user cannot click on the buttons whilst the external swf is showing.

Any help will be super appreciated!!!

Thanks in advance!
