Shadow in IE is not displaying properly

Hi,

I am using jQuery UI 1.6rc6, the shadow in the jQuery dialog is not

visible in all the sides, it is only visible in the top and left of the dialog.

My sample code for the dialog box is as below.

$(document).ready(function () {

$('#testCode').dialog({

autoOpen: false,

bgiframe: true,

modal: true

});

});

The dialog is working fine in all other browsers like Firefox, Opera, Chrome and Safari but in IE the shadow is visible only in the left and top. In IE by default the height of the dialog is not the same as the other browsers.

Thanks
