Agreed, that was over simplified.
I probably should have said clearly I was using "global" in a rather loose
way -- as opposed to function local; that's why I put the quotes. I just
wanted to point out what the problem was in the original question, in a
simple way, without getting into activation objects and other stuff.
Thanks for your clarifications.
