File not found error

I can't figure out how to fix the file not found error that I'm getting. "... failed to open stream: No such file or directory..." I've looked for answers all over the net and can't find anything that seems to help. Basically I only get the error when using relative paths. My PHP include_path is set to ".;c:\php\includes". Absolute paths work just fine. I know my PHP is at least mostly configured correctly. I say mostly because I run Gallery (which uses PHP) on my server and it works just fine but I cann't run either phpBB2 or MediaWiki because they use relative paths for includes. phpBB2 does work when I change relative to absolute but I don't want to go through and edit ever single file... plus upgrades will be a pain. So anyone run into this problem and solve it? Thanks. - Alex some phpinfo: PHP Version 5.2.0RC3-dev Build Date Aug 31 2006 20:16:01 Configure Command cscript /nologo configure.js "--enable-snapshot-build" "--with-gd=shared" Server API Apache 2.0 Filter Virtual Directory Support enabled Configuration File (php.ini) Path C:\php\php.ini PHP API 20041225 PHP Extension 20060613 include_path .;c:\php\includes .;c:\php\includes
