The alternative is on the follow up page itself, you can add a "frame breaker" code so no matter what it goes to it's own page.
I found this code as an example on http://www.thesitewizard.com/archive/framebreak.shtml:
<head>
<script language="JavaScript" type="text/javascript">
<!--
function breakout_of_frame()
{
// see http://www.thesitewizard.com/archive/framebreak.shtml
// for an explanation of this script and how to use it on your
// own website
if (top.location != location) {
top.location.href = document.location.href ;
}
}
-->
</script>
</head>
