Windows: Can't open PHP files on my server -- get a dialog box instead

Hi everyone / anyone,   I'm a newbie to PHP and configuring my machine to run it. Here's my situation: - Any time I try to open/test a PHP file (located on my machine) on my browser (IE7) the response I get is the dialog box that says "Do you want to open or save this file?" - I can open (view) PHP sites on the web no problem - My OS is WinXP Pro (latest updates applied) - I'm running IIS 5.1 as my web server - MySQL is running and the TCP port 3306 is open - I installed PHP 5.2.5 using the msi installer - I've rebooted - My permissions and system variables appear to be properly set up Any suggestions on what next steps I can take? Thanks, Leyts __________________________________________________________________ Get the name you've always wanted @ymail.com or @rocketmail.com! Go to http://ca.promos.yahoo.com/jacko/
