If you have an ASP.Net Dropdown list on a form and you use radFormDecorator, the dropdown list does not work correctly.  You can click the button to expand the dropdown list.  If you click the button again, the list should collapse, but it doesn't.  This is observed on IE9 and latest Firefox.  It is observable on your demo page at : http://demos.telerik.com/aspnet-ajax/formdecorator/examples/overview/defaultcs.aspx
