One way to "capture back" a visitor is to have your links set to open in a
new window. When closed, you site is still there.

describes two methods.

And if you choose to use the ECMAScript code approach note that the first
javascript code snippet is incorrect on the website. Use this instead:

<script language="JavaScript" type="text/javascript">function Show(Url,
Name, Features) { window.open(Url, Name, Features); }</script>
