Also do the same for ../includes/modules/product_listing.php so that the button is greyed out when the products are listed, ie., (about line 147)
[color=green]
case 'PRODUCT_LIST_BUY_NOW':
  $lc_align = 'center';
  if (tep_get_products_stock($listing_values['products_id'])> 0)
  {
     $lc_text = '<a href="' . tep_href_link(basename($PHP_SELF), tep_get_all_get_params(array('action')) . 'action=buy_now&products_id=' . $listing_values['products_id'], 'NONSSL') . '">' . tep_image_submit('button_in_cart_small.gif',
              TEXT_BUY . $listing_values['products_name'] . TEXT_NOW) . '</a>&nbsp;';
            }
            else
            {
              $lc_text = tep_image_button('button_in_cart_small_faded.gif').'&nbsp;';
            }
            break;[/color]
