anybody knows how to make the jquery dialog not resizable ? I call it like this atm :

 var elem = $("#mydiv");
        elem.dialog({       
        modal: true,
        title: 'title',
        buttons: {
            Ok: function() {
                $(this).dialog('close');                                
            } //end function for Ok button
        }//end buttons
            });  // end dialog  
            elem.dialog('open');
