Druapl Mania

I'm working on getting Drupal to work as a CMS for BYU. I've learned a lot in the last few weeks of work. Right now I'm working on the menuing system. We want drop down menus. I built one from scratch using the yui, but alas, it wasn't cross-browser compatible, which really stinks. So now I'm trying out using yui's menu class as the base. I'm over-ridding some of Drupal's themeing functions to get it to work. Here's what I have so far:

 /**
* Generate the HTML for a menu tree.
*
* @param $pid
*   The parent id of the menu.
*
* @ingroup themeable
*/
function byu1_menu_tree($pid = 1, $level = 0) {
 if ($tree = byu1_menu_tree_improved($pid, $level)) {
   return "\n
\n
\n
\n". $tree ."\n
\n
\n";
 }
}


/**
* Returns a rendered menu tree.
*
* @param $pid
*   The parent id of the menu.
*/
function byu1_menu_tree_improved($pid = 1, $level = 0) {
 $menu = menu_get_menu();
 $output = '';

 if (isset($menu['visible'][$pid]) && $menu['visible'][$pid]['children']) {
   $num_children = count($menu['visible'][$pid]['children']);
   for ($i=0; $i < $num_children; ++$i) {      $i == 0 ? $level++ : '';       $mid = $menu['visible'][$pid]['children'][$i];       $type = isset($menu['visible'][$mid]['type']) ? $menu['visible'][$mid]['type'] : NULL;       $children = isset($menu['visible'][$mid]['children']) ? $menu['visible'][$mid]['children'] : NULL;       $extraclass = $i == 0 ? 'first' : ($i == $num_children-1 ? 'last' : '');       $output .= theme('menu_item', $mid, menu_in_active_trail($mid) || ($type & MENU_EXPANDED) ? theme('menu_tree', $mid, $level) : '', count($children) == 0, $extraclass, $level);        $i == $num_children - 1 ? $level-- : '';      }   }    return $output; }    /**  * Generate the HTML output for a single menu item.  *  * @param $mid  *   The menu id of the item.  * @param $children  *   A string containing any rendered child items of this menu.  * @param $leaf  *   A boolean indicating whether this menu item is a leaf.  *  * @ingroup themeable  */ function byu1_menu_item($mid, $children = '', $leaf = TRUE, $extraclass = '', $level) {   return '
'. menu_item_link($mid, TRUE, $extraclass) . $children ."
\n";
}

Cannot Find NoniGPSPlot

I was getting the "cannot find NoniGPSPlot" error on the mio. It was remedied by downloading http://hautil.free.fr/bm/PackDll2006.zip and placing it's contents in the program's folder.
