I have a <?php print $search_box; ?> in my page.tpl.php page. On pages that exist, the search works, but on 404 pages, it does not.

I saw some bugs/patches threads over at drupal.org for D6.15, but none of them seem to work according to the thread and they weren't really relevant to D5.x

I have a theory that the because the <?php print $search_box; ?> creates a form with an action to itself(a non-existant page), it'll get the 404.

Has anyone run up against this? If so, how did you fix it?

One theory I has was to somehow tap into the form and always make the action="/" (front page) which would always exist.

If this is a good idea, how does one go about tapping into the FormAPI and overwriting the action? Is it a preprocess function?
