trouble with apache 2.0.44 and php 4.3.1 on FreeBSD and index.php

I've been trying to upgrade my Apache (1.3.xx to 2.0.45) and PHP (from ??? to 4.3.1) installations on my FreeBSD 4.4 machine mostly with success, but I'm running in some strange things... I've added the following lines to my httpd.conf LoadModule php4_module libexec/apache2/libphp4.so AddType application/x-httpd-php .php AddType application/x-httpd-php-source .phps and DirectoryIndex index.php index.html index.html.var and when I attempt to go to my server after restarting using /usr/local/sbin/apachectl restart (on the freebsd machine) and then try to open the page from a win2k machine on the lan., I get a flash of a download dialog, and then it goes away and the web browser doesn't stay open... if I remove the index.php from the line DirectoryIndex index.php index.html index.html.var then I get a dir listing on the server... Is there something broken? or is there a goofy config setting I should be adding. I recall I had some trouble getting Apache1.3 working with PHP before as well. Thanks, Jeff.
