Nick,
I have tested Peter's problem #1 and occurs the same to me.

This is the reason i've not answered to him.

I suppose that enabling optimistic buffering to form, it assumes that is row buffering, not table buffering. In order to work with getnextmodified i must especifically set buffering to each table.
