You're probably using the -unique option. That changes the meaning
of the "id" field in the html table. The default search script displayed
"id" as the last updated time instead of "Visited".
You can download a newer default search script at: http://www.thunderstone.com/webinator/search
or change:
<H6>Last Updated: $When</H6>
to:
<H6>Last Updated: $Visited</H6>
in the "context" function of your current script.
