Help Please

Hello Again Everyone, Thank you to those of you who sent me suggestions. Unfortunately none so far have solved the problem. I think I need to give you more information. I am running a Mandrake 8.3 linux box. Apache 1.3.23. PHP 4.2.1-8mdk. Installed from RPM's. PHP shows in my active list of modules on Webmin. I am trying to get Squirrelmail working. I have added fake directory aliases for it to httpd.conf so that apache thinks it's /squirrelmail. When I comment out the following two lines in httpd.conf that tweak mime extensions, "AddType application/x-httpd-php .php" "AddType application/x-httpd-php-source .php" the behavior no longer happens, namely, when I invoke /squirrelmail/index.php my browser then asks me where I would like to download it to. Actually, it does this when I invoke any file ending in .php. What I get is the following. "You have chosen to download a file of type: application/x-httpd-php from httpd://localhost/squirrelmail/ What should Mozilla do with this file?" And a list of choices as to where I would like to keep it. Internet Exploder also offers to save the file somewhere. What's supposed to happen is that I get the Squirrelmail login screen. Has anyone seen this behavior before? Is there any more information needed by anyone that might be able to tell me what to change to make this work properly? I know it's something simple. But I have no idea what. Come to think of it, this might be an apache question. Either way, any help is greatly appreciated. Thanks very much in advance; Paul Kelly
