This is what I did. I do like Google to spider and crawl my site so I wasn't happy with the "nofollow" option. You can change the showPathway stuff to the following in your product_detail templates:
<?php
if( $this->get_cfg( 'showPathway' )) {
echo "<div class=\"pathway\">$navigation_pathway</div>";
}
if( $this->get_cfg( 'product_navigation', 1 )) {
$search_text = $previous_product_url;
$look_for = "?pop=0";
$change_to = "";
$prev_url = str_replace($look_for, $change_to, $search_text);
$search_text2 = $next_product_url;
$look_for2 = "?pop=0";
$change_to2 = "";
$next_url = str_replace($look_for2, $change_to2, $search_text2);
if( !empty( $previous_product )) {
echo '<a class="previous_page" href="'.$prev_url.'">'.shopMakeHtmlSafe($previous_product['product_name']).'</a>';
}
if( !empty( $next_product )) {
echo '<a class="next_page" href="'.$next__url.'">'.shopMakeHtmlSafe($next_product['product_name']).'</a>';
}
}
?>
