Apache calls initialize module twice

[Nasko]

Hello guys.       I'm running Apache2 on WindowsXP as a service (path to executable = "c:\apache2\Apache.exe" -k runservice in my service configuration ) .       I have also ap_hook_post_config  (initialize_module,  NULL,NULL,APR_HOOK_MIDDLE ) in my source code...       The problem I have is that when run as a service initalize_module() is called twice.     However when I debug in Visual C++ and call Apache2 with  -X , initalize_module() is called only once !!!!     Any ideas how to avoid the second call to initalize_module when I run as a service ?   Thanks in advance, Nasko
