var mc:MovieClip = new MovieClip();
	mc.buttonMode = true;
	mc.addEventListener( MouseEvent.CLICK, trackEventHandler, false, 0, true );

function isProductionMode():Boolean
{
	var runtimeEvironment:String = Capabilities.playerType;

	if (runtimeEvironment == "External" || runtimeEvironment == "StandAlone"){
		return false;
	} else {
		return true;
	}
}

function trackEventHandler( e:Event ):void
{
	//If the Complied Flash Player is on the HTML page, give it a Page View
	if( isProductionMode() ){
	    navigateToURL(new URLRequest("analytics._trackPageView()"), '_self');
	}
}

There are many ways to tweak this code but hopefully this will get you all started.  Whenever I'm tracking PageViews or Events for something like Google Analytics, I don't want navigateToURL() to interfere while I'm developing.  These two functions will keep navigateToURL() from trying to load a Browser page until the SWF is loaded into an HTML page
