Unfortunately the site in question is an Adult Webmaster's resource site so I can't post the link on this forum. If you want to see the problem for yourself go to the ssLinks demo site and click on the link to "PornoItalia" on the "Site's using ssLinks" page.
<form action=links.php method=post name=rate1>
<input type=hidden name=action value=rate>
<input type=hidden name=id value=1>
<select name=score size=1 class=small onchange="document.rate1.submit()">
If anyone has any ideas as to why this is happening I'd love to hear them.
