PHP 5.2 and MySQL on IIS

I originally sent this message to the general list, but maybe it's more appropriate here... I have just installed PHP 5.2.4 on Windows 2003 machine running IIS. Everything is fine except when I try to enable the MySQL extension (either php_mysqli.dll or php_mysql.dll), when I do a php_info(), at the bottom I get the message "Error in my_thread_global_end(): 1 threads didn't exit". All my other extensions (curl, MSSQL, Oracle, etc.) load fine. It's only when trying to enable this one. I did a manual install, using the php-5.2.4-Win32.zip. This contains versions 5.2.4.4 of php_mysql.dll and php_mysqli.dll. I found a thread where someone said they fixed this by disabling php_iisfunc in the php.ini, but my php.ini doesn't even have this in it. Any ideas? Thanks. Regards, Bruce Regards, Bruce
