Button w/in movie clip not working

Question

I know this question has been raised before and it usually
just boils down to using the frame #'s and labels. But, even with
that it is not working.
I have a map of the US and when each state is rolled over I
would like a menu to appear - this menu is a list with several
options and all of the options are buttons. I have it set up so
that each state is its own MovieClip and each has an invisible
button over it for the hit area and the menu to appear. (i didn't
want it to be simply when it rolls over the state movie clip
because the hit would be square, covering other states and causing
a mess of pop up menus)
Anyway, the menu pops up fine, but the buttons within do not
work. Any ideas of what I'm doing wrong? Thanks Much!!!!
wi_mc.stop(); // wi_mc is the state movie clip
wi_btn.onRollOver = function(){ //wi_btn is the invisible
button
wi_mc.gotoAndStop(15); //frame 15 is where my menu resides
wi_btn.useHandCursor = false;
wi_mc.onRollOut = function(){
wi_mc.gotoAndStop(1);

Alright, I've made adjustments to how I've got it all set up.
I've made the menu it's own swf file, (seeing as how I'm going to
have 48 of them in total I figured it was less messy to have each
as their own file). Anyways... here's the current problem and I'm
hoping someone has a good explaination for why this would be
happening...
on my main file I have 2 invisible buttons - 1 is calling the
movie to load when rolled over and the other is calling the movie
to unload when a roll-out occurs. RollOver works great - fully
functional menu shows up. Roll out, however, is having some issues.
The invisible button is in the same location of the menu, same size
etc. so that when the user rolls away from this the menu should
"unload".
For some reason it's acting as if the hit area for the roll
out is off. I did a trace to find out where it's saying the rollout
areas are and the first is actually when I roll onto it, then only
again when i roll out from the left side of the graphic. I've tried
deleting the button and creating a new one but the same thing is
happening.
Any ideas for a very confused person trying to complete this
simple task of unloading a swf via rollout? MUCH appreciated!!!!
this.createEmptyMovieClip("ExternalSWFHolder",
this.getNextHighestDepth());
var SWFLoader:MovieClipLoader = new MovieClipLoader();
wi_btn.onRollOver = function(){
SWFLoader.loadClip("wi_menu.swf", ExternalSWFHolder);
wi_rollout.onRollOut = function (){
SWFLoader.unloadClip(ExternalSWFHolder);
