Loading Extensions Problem

Hi.. I'm trying to activate some external extensions that come with the PHP Zip file (Win32). I've had this problem in 4.0.4 and 4.0.4pl1. I go in the PHP.INI file and define the extensions directory, and un-comment the extension I need to have loaded, in this case, php_imap.dll. When I run a test script I have viewable over the web to run the php_imap.dll extension on the client side, I get an error on the server side consisting of this: WARNING: imap: Unable to initialize module Module compile with debug=0, thread-safety=1 module API=20000809 PHP compiled with debug=0, thread-safety=1 module API=20001214 These options need to match. How can I fix this? Thanks, --Marc Clerc
