Dialog boxes initially display even with autoOpen: false

Hi

in the site uxfin.com i have some text content in the top 3 menu bar buttons. Though set to autoOpen: false - the page initially displays the contents and then hides after quite a delay. Is there a way to overcome this behaviour or should I change my design.

Code snippet...

    html break.
        html div  
                id: ( id := html nextId );
                script: ( html jQuery new dialog
                        title: 'Lightbox Dialog 1';
                        autoOpen: false;
                        modal: true );
                with: [ self renderUsersGuide: html ].
        html anchor
                onClick: ( html jQuery id: id ) dialog open;
                with: 'Open lightbox 1'.

regards
Sanjay
