Problem with JQuery UI and Recaptcha

Problem with JQuery UI and Recaptcha


Hi,
I am trying to integrate Recaptcha onto my site which is using JQuery.
I tried to use a blind effect on it created using the JQuery UI Plugin
but it does not work: the reCaptcha begins to appear and the page
becomes suddenly blank. It works in Safari but fails elsewhere.
It seems that the problem comes from the <script></script> part of the
code below that I want to toggle:
<script type="text/javascript">
    $(function() {
        //run the currently selected effect
        function runEffect(){
            //run the effect
            $("#effect").toggle("blind",500);
        };
        //set effect from select menu value
        $("#button").click(function() {
            runEffect();
            return false;
        });
    });
    </script>
</head>
<body>
<div class="demo">
<div class="toggler">
    <div id="effect" class="ui-widget-content ui-corner-all">
        <h3 class="ui-widget-header ui-corner-all">Toggle</h3>
        <script type="text/javascript" src="http://api.recaptcha.net/
challenge?k=APIKEY"></script>
    </div>
</div>
<a href="#" id="button" class="ui-state-default ui-corner-all">Run
Effect</a>
</div>
Any ideas ?
Thank you.
