flash + javascript enabled browser back but error on lauching lightbox

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: http://www.campbelltest.co.uk/britishMuseum/online/

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 -->

Code (markup):

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>

Code (markup):

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!!
