That's what I thought too.
Therefore it makes no sense to me, that Netscape refrains from working with $FileObj->run(); enabled.
When opening a page, let's call it index.php, it should include template.html, where a heading and a left and a right "frame" are defined.
Without $FileObj->run(); index.php runs fine, though without the inclusion of template.html.
In any case the title of the page, which is defined in template.html, is read in displayed correctly. Moreover the code of the page is displayed correctly in the browser window.
I use the Apache Webserver with MySQL. Maybe there is the problem?
