Completely remove a class instance? (EventListeners etc..)

programming flash

Hello there!
I’ve struggled another problem, this time it’s about a class instance that keeps working*(EventListeners still going)* even when I’ve used removeChild and null’d the instance.

Here are my classes I use:

private var frame_splash:Splash;
private var frame_gameStart:GameStart;
private var frame_gameOver:GameOver;
private var frame_levelSelect:LevelSelect;

This is how I display them (Just showing the splash_screen):

public function show_splash():void {
    removeInstances();
    frame_splash = new Splash(this);
    addChild(frame_splash);
}

And the function removeInstances():

private function removeInstances():void {
    if (frame_splash) { 
        removeChild(frame_splash); 
        frame_splash = null;
    }
    if (frame_gameStart) {
        removeChild(frame_gameStart);
        frame_gameStart = null;
    }
    if (frame_gameOver) {
        removeChild(frame_gameOver);
        frame_gameOver = null;
    }
    if (frame_levelSelect) {
        removeChild(frame_levelSelect);
        frame_levelSelect = null;
    }
}

As far as I understand, removeChild will only remove the child on the stage (the visible stuff), and the by setting the instance to null, will only remove the access from the instance, becuase when I look at the output I can see the game still tracing stuff about the game *(that’s not being displayed becuase of removeChild)
*
What would be the best way to remove/stop/hide the EventListeners, visible childs etc.?

Thanks in advance,
Tompa
