[flexcoders] Can't remove an object?!

[Nate Pearson]

I'm adding this opaque loading overlay to my application when it
loads.  It's just a VBox.  I'm pulling out my hair, any help is
greatly appreciated!

Here's what I do:

private var listLoadingOverlay:LoadingOverlay = new LoadingOverlay()

private function addLoadingOverlay():void{
        listLoadingOverlay.height = 332;
        listLoadingOverlay.width = 588;
        listLoadingOverlay.y = 30
        listLoadingOverlay.x = 1

        this.addChild(listLoadingOverlay)
}

private function removeLoadingOverlay():void{
        this.removeChild(listLoadingOverlay)
}
