If you prefer to have a single event handler for the mouse events, you can use this instead of “MC_MOUSE_OVER”, “MC_MOUSE_OUT” etc.

navigationManager.addEventListener(NavigationEvent.MC_STATE_CHANGE, btnsFadeOutHandler);
function btnStateChangeHandler(event:NavigationEvent) {
    switch (event.params.state) {
        case "activate" :
	    // Your code
	    break;
	case "mouseOver" :
	    // Your code
	    break;
	case "mouseOut" :
	    // Your code
	    break;
	case "deactivate" :
	     // Your code
	    break;
    }
}
