How to make a frame1 in the timeline, to be my startpage, when I already have a frame on the first timeline?
myStartClip.visible = true;

var startContainer:Sprite = new Sprite();
addChild(startContainer);  // and maybe position it with x and y

var infoTf:TextField = new TextField();
infoTf.text = "some game description and how to play";
var bg:SomeBackground = new SomeBackground();
var startBtn:SomeBtn = new SomeBtn();
startBtn.addEventListener(MouseClick.CLICK, handleMClick_startGame);

startContainer.addChild(bg);  // add the other things too of course
