This code works with blogs also!

uninav_nodeapi function should be replaced with this code:

function uninav_nodeapi(&$node, $op, $arg) {
  switch ($op) {
    case 'view':
      if($node->nid) {
           $node->node_url=drupal_get_path_alias("node/".$node->nid);
           if(function_exists("book_load")) {
              if($node->type=='book') $node->book = TRUE;
              else $node->book = book_load($node);
           }
           if($node->tid) $tid=$node->tid;
           elseif(arg(0)=='taxonomy' && arg(1)=='term' && is_numeric(arg(2))) $tid=arg(2);
            if($tid && !$node->book && $node->type!='image' && !$node->event_start && $node->type!='blog') $node->node_url.="?tid=$tid";
           $node = theme('crossnuke_node_navigation', $node);
      }
      break;
  }
}
