Superfish menu issue

Hi,

There is a bug in superfish menu. If you have 5 or 6 parent menu with child inside and if you try to expand all one by one, then every parent menu dose not get expanded. It gets expanded for first or last menu in the column. Could you please fix it? Because I'm not able to expand all child menus of my site. Those child will only expand if you click on the parent and open the page.

Thanks
