[chinmasterj]

Hello Everbody,

I have been at this problem for 10 hours now and am going NUTS!! I am making website to look around an ancient Egyptian Tomb. Feel free to have a look:

I have a flash movie which I have scripted to utilise the browser back button using this script

http://www.asual.com/swfaddress/docs/

This works fine until open a lightbox image form within the flash movie using Lokesh Dhakar Light box

http://www.lokeshdhakar.com/projects/lightbox2/

and the browsers back button stops working!!

The code below is to the JavScript links and the code that lauches the lightbox:

<script type="text/javascript" src="js/swfaddress-optimizer.js"></script>
        <script type="text/javascript" src="js/swfobject.js"></script>
        <script type="text/javascript" src="js/swfaddress.js"></script>
        <script type="text/javascript" src="js/swfmacmousewheel.js"></script>
        <script src="js/prototype.js" type="text/javascript"></script>
		<script src="js/scriptaculous.js?load=effects" type="text/javascript"></script>
        <script src="js/lightbox.js" type="text/javascript"></script>
        <!-- start | JC -->
        <!-- added for flash -->
        <!-- added for launch from flash -->
        <script language="JavaScript">
            function openLightbox(url,group){
				var objLink = document.createElement('a');
				objLink.setAttribute('href',url);
				objLink.setAttribute('rel','lightbox['+group+']');
				objLink.setAttribute('title','caption');
				Lightbox.prototype.start(objLink);
            }
        </script>
        <!-- end | JC -->

This code is how I have embeded the flash in the page:

<script type="text/javascript">
    		var so = new SWFObject('container04.swf', 'container04', '760', '450', '8', '#ffffff');
            so.useExpressInstall('js/expressinstall.swf');
    		so.addParam('menu', 'false');  
			//so.addParam('movie','container04');       
    		so.write('flashcontent');
    		var macmousewheel = new SWFMacMouseWheel( so );
    	</script>

I have added a text box to movie that shows the back button function exicuting and what its exicuting. I have never done any work with JavaScript before so I am up the creek without a paddle!!
