MathAdor,
Have you considered solutions that don't involve event handlers available to AS3.
If I understand correctly you are trying to:
1.  Control buttons that exist in your main .swf file
2.  Control the visibility of those buttons from a child .swf called into existence from the main .swf file
You could control this completely from the child .swf by setting a variable for your parent .swf
In your child .swf creat a variable that contains the parent movieclip:
var myParentClip:MovieClip = MovieClip(parent.parent);
Now control your buttons with the appropriate command from your child
myParentClip.buttonName.visible = true;
myParentClip.buttonName.visible = false;
Total control from your child .swf
Hope this helps
