Does RI with nullable FKs really work?????



I've taken RI off all my relationships in which the foreign key can be null,
because Access doesn't seem to allow a FK to be null if RI is defined on it.

I'd be amazed if Access did not permit RI on nullable FKs, so first thing is
to ask the experts here: does it?

If the answer is "yes", then I'll post the details of my own situation, in
which I can't leave a FK null if RI is defined on it.

thanks.
