After installed windows modules "php_xdebug-2.0.0rc3-4.4.1.dll" downloaded from xdebug.org, I begun to play with profiler than trace features.

While I've no problem with profiler configuration settings with Apache .htaccess file, I run in trouble with trace settings.

I used three cases of config thru a PHP script

1. xdebug_start_trace();
   ==> produce a "trace.{hash}.xt" file into c:\wamp\php4\profiler dir as defined by .htaccess

BTW I got a hash while "xdebug.auto_trace" is set to "Off" (doc tell opposite purpose) !

2. xdebug_start_trace(FILE);
   ==> produce a "{FILE}.xt" file into script dir

NOTICE no hash appended here, while dir is script location "c:\wamp\www" and not .htaccess expected trace_output_dir

3. xdebug_start_trace("myscript");
   ==> produce no trace XT file (nowhere)

I got the same result with windows module PHP 5.2
