In UI/Dialog options "shadow: false" show error

In UI/Dialog options "shadow: false" show error


Hi,
I am using the jQuery UI 1.6rc2, when I use the following sample code
I am able to drag my dialog box.
<script>
$(document).ready(function(){
$("#dialog").dialog({
resizable: false
});
});
</script>
Now, if I add the option "shadow: false" to hide the shadow of the
dialog, the shadow disappears but when
I try to drag the dialog I get an error message as "this.shadow is
undefined".
Please let me know if I am going wrong with the following code, or if
it is a bug.
<script>
$(document).ready(function(){
$("#dialog").dialog({
shadow: false,
resizable: false
});
});
</script>
