Zend Studio changing my include_path?

Hi All, I've been having a very strange problem wihen debugging within Zend. I echo get_include_path() at the top of each php files. In a browser, the correct include_path is displayed as defined in my php.ini. However, when debugging in Zend Studio, the incliude path shows as ".;C:\php5\pear". There is no C:\php5 folder on my machine and my scripts are failing. Has anyone seen this? How do I make Zend respect the settings in the php.ini file? Thanks, Steve
