Fullscreen troubles

1

so i’m trying to make a fullscreen button for my flv player, and it only works when my fullscreen_btn.x is < 600 and > around 300. anybody ever encountered this before?


	// Full screen
	var fullscreen_btn:fullscreenBtn = new fullscreenBtn();
	controls_mc.addChild(fullscreen_btn);
	
	// doesn't work unless it's around 600
	fullscreen_btn.x = 925;
	fullscreen_btn.y = 4;
	fullscreen_btn.buttonMode = true;
	fullscreen_btn.addEventListener(MouseEvent.MOUSE_UP, fullscreener);
	function fullscreener(event:MouseEvent):void{
		if (stage.displayState == StageDisplayState.NORMAL) {
			stage.displayState = StageDisplayState.FULL_SCREEN;
			stage.align = StageAlign.TOP;
		} else {
			stage.displayState = StageDisplayState.NORMAL;
		}
	}

help is greatly appreciated
