[FX.php List] FMS Server Console gets whacky/ CWP fails under IIS

[Joel Shapiro]

Hey Jonathan

I've got no answers to your problem, but here's a list of FMServer  
error codes:
http://thefmkb.com/7275

Also, according to:
http://forum-en.filemaker.com/fm/board/message?board.id=us-fms&thread.id=2604
Error 22 gets produced when a server-side script ends.
