How can I close it and maintain the scroll position?

2. $("#dialog-container").dialog({
3.                 title: "MyTitle",
4.                 width: 'auto',
5.                 height: 'auto',
6.                 modal: true,
7.                 open: function () {
8.                     jQuery('.ui-widget-overlay').bind('click', function () {
9.                         jQuery('#dialog-container').dialog('close');
10.                     });
11.                 }           
12.             });//End dialog

For some reason and occasionally it keeps the scroll position.

I'm trying to figuring out why this sometime works, but I don't seem to find a reason.
