You have to create an empty div on every page:

    <div id="lightbox">
    </div>

Using the updater you can fill it with something like this:

    <div id="lightbox">
       <div id="overlay"></div>
       <div id="dialog">[ your dialog ]</div>
    </div>

By emptying the div again:

    <div id="lightbox">
    </div>

You might want to use an onAnswer: callback.
