.load Content loading from other html-page working in Dreamweaver, but not in Safari

Hi there, 

i have a problem loading a div/whole page from an external page with jquery. I use the following code:

<script type="text/javascript">
$(document).ready(function() {
$("#comercial").click(function() {
$("#loadgallery").load("gallery.htm").hide().fadeIn('slow');;
});
});

});
</script>

It works fine in Dreamweaver CS5, but not in Safari (4&5), can anyone help me out ?
