I've got a few demo videos I've been making as tutorials, and I'm using a link to open a dialog box and put the demo video in that box.

I use the same div to show other notes on the page when a user selects to view a complete note.

The code I use to show the notes is

    jQuery('span.Notes').live('click', function(){
var note=jQuery(this).data('note');

    jQuery('div#showNote').text(note);
       jQuery('div#showNote').append('
');

    jQuery('div#showNote').dialog({
      modal: true,
      close: function(){
      jQuery('div#showNote').dialog('destroy').empty();
        }
    });

    });

The code I use for the demo videos is VERY similar.

 jQuery('a.demoVid').click(function(){
         var videoUrl=jQuery(this).attr('href');
       jQuery('div#showNote').dialog({
       modal: true,
    height: 400,
    width: 480,
    close: function(){
    jQuery('div#showNote').dialog('destroy').empty();
    }
    });
    swfobject.embedSWF(videoUrl,'showNote','480','390','8.0.0');
 return false;
 });

I can click on as many notes as I want, and the dialog opens up and shows the note. However, when I click the demoVid, the dialog opens, but then closing the dialog kills any other 'showNote' dialogs on the page, so I can't open any more notes, or demo videos.
