Jason, I have to say most of that went straight over my head. Which sources
do I alter? And more importantly where in the sources do I alter the code?

BTW I'm using 4.2Ef IBO and also, I have KeyLinksAutoDefine set to false, I
have KeyRelation set to KEY_NO (which is the IB primary key for the table).
I have nothing in the KeyLinks strings. What should go in there?

Regards,
Andy.
