    fixed this in another post
 * for wp3.2
    wp-content/plugins/wp-calendar/fsCalendarAdmin.php change this : add_action(‘
   admin_print_footer_scripts’, ‘wp_tiny_mce_preload_dialogs’, 30 ); to this : add_action(‘
   admin_print_footer_scripts’, ‘wp_preload_dialogs’, 30 );
 * and give me feedback (works for me)
