Popup aggravation - help needed

1

I’m having a problem destroying a pop-up.
The window creates beautifully, but does not close on click of the ‘x’.

Any and all help appreciated.

Here’s the code


buttonListener = new Object();
buttonListener.click = function(){
  myWindow = mx.managers.PopUpManager.createPopUp(_root, mx.containers.Window, true, { closeButton: true, title:"Change Password", contentPath:"test_mc"});
  myWindow.setSize(275,110);
}
advanced_btn.addEventListener("click", buttonListener);
closeWin = new Object();
closeWin.click = function(){
   myWindow.deletePopUp();
}
myWindow.addEventListener("click", closeWin);
