Thanks again Sietse. I think it will be easier for me to go with the Error
Procedure and create a new base class on which to base all my objects. I can
then just code the 1 error routine. Should be easier than decoupling all of
my objects. Ouch!
I still intend to learn more about design patterns as I have been putting it
off for too long. I googled mediator but still didn't make things much
clearer. Just off to order my copy of that book.
Regards
Darren
PS. Interesting that the VFP6 com server did not have a problem with this.
