I have project settings that indicate I have a PHP interpreter with XDebug 2.2.3 installed and enabled (as reported by PHPStorm). I have the Chrome extension (XDebug Helper 1.4.2) that I have enabled (the bug is green). I have clicked on the icon to listen for PHP debug connections on the IDE. Yet when I set a breakpoint it never gets hit.When I build a small sample program debugging works just fine but with a larger set of source code (of which the "project" is a small subset) I cannot get any breakpoints to be hit. Ideas?
