Combo box visible and loaded but cant interact with it

Question

I have two swf files onSiteSearch and onSiteReg. Both work as
expected when used alone but when onSiteReg is loaded from onSite
Search the comboBox on onSiteReg cannot be interacted with. It is
visible and has the correct data in it but there is no ability to
drop down the comboBox. I have tried many suggestions I have found
here including making sure there is an instance of the comboBox in
the onSiteSearch but nothing seems to change.
The onSiteSearch brings up a dataGrid and when a list item
from the grid is click it loads the onSiteReg (see code below).
Everything works as it should including checkBoxs and actionScript
but I can change the selected choice in the comboBox.
Thanks in Advance for any insight and/or help.
var dgListener:Object = new Object();
dgListener.cellPress = function(event) {
txtTalentEventID.text =
dgResults.getItemAt(event.itemIndex).TalentEventID;
_global.thisTalentEventID =
dgResults.getItemAt(event.itemIndex).TalentEventID;
loadMovie("onSiteReg.swf",_level0);
dgResults.addEventListener("cellPress",dgListener);

Answer 1

Ok. I changed the code to use loadMovieNum like this:
var dgListener:Object = new Object();
dgListener.cellPress = function(event) {
txtTalentEventID.text =
dgResults.getItemAt(event.itemIndex).TalentEventID;
_global.thisTalentEventID =
dgResults.getItemAt(event.itemIndex).TalentEventID;
//loadMovie("onSiteReg.swf",_level0);
loadMovieNum("onSiteReg.swf", 2);
dgResults.addEventListener("cellPress",dgListener);
and now the onSiteReg comboBox works fine but now i have both
movies on the screen at the same time and can't figure out how to
get rid of onSiteSearch.
Yes, I am new to this flash stuff. Have been doing CF since
