PopupManager - depth problem

I put the MC that contains the script for creating a window inside of another MC. When I do that, the script does not create a new window. Why? I have the window component in the library of the childMC and the below script is in the childMC. The openBTN creates a window when childMC is not inside parentMC.

Is this a “KnownIssue”?

var addWin:MovieClip = PopUpManager.createPopUp(_root, Window, true, {closeButton:true, contentPath:"addMC"});
    var winListener:Object = new Object();
    winListener.click = function(evt_obj:Object) {
        addWin.deletePopUp();
    };
    winListener.complete = function(evt_obj:Object) {
        addWin.setSize(addWin.content._width, addWin.content._height + 25);
    }
    addWin.addEventListener("click", winListener);
    addWin.addEventListener("complete", winListener);
    addWin.title = "Add New Submenu"
    addWin.move((Stage.width/2)-addWin._width,(Stage.height/2)-addWin._height)
