ok Thanks so much for responding. I think I just found a fix for it by putting this code into the functions.php and changing afew items. For my case I have two custom post types ‘motion’ ‘still’.

here is some code I found…

// As of WP 3.1.1 addition of classes for css styling to parents of custom post types doesn't exist.
// We want the correct classes added to the correct custom post type parent in the wp-nav-menu for css styling and highlighting, so we're modifying each individually...
// The id of each link is required for each one you want to modify
// Place this in your WordPress functions.php file

function remove_parent_classes($class)
{
  // check for current page classes, return false if they exist.
	return ($class == 'current_page_item' || $class == 'current_page_parent' || $class == 'current_page_ancestor'  || $class == 'current-menu-item') ? FALSE : TRUE;
}

function add_class_to_wp_nav_menu($classes)
{
     switch (get_post_type())
     {
     	case 'motion':
     		// we're viewing a custom post type, so remove the 'current_page_xxx and current-menu-item' from all menu items.
     		$classes = array_filter($classes, "remove_parent_classes");

     		// add the current page class to a specific menu item (replace ###).
     		if (in_array('menu-item-592', $classes))
     		{
     		   $classes[] = 'current_page_parent';
         }
     		break;

     	case 'still':
     		// we're viewing a custom post type, so remove the 'current_page_xxx and current-menu-item' from all menu items.
     		$classes = array_filter($classes, "remove_parent_classes");

     		// add the current page class to a specific menu item (replace ###).
     		if (in_array('menu-item-348', $classes))
     		{
     		   $classes[] = 'current_page_parent';
               }
     		break;

      // add more cases if necessary and/or a default
     }
	return $classes;
}
add_filter('nav_menu_css_class', 'add_class_to_wp_nav_menu');

Piet, I am having the same problem, I’ve read a lot about fixes but I haven’t quite figured it out. Could someone please give us some insight? Any help will be greatly appreciated! Thanks!
