[AccessD] Ooops!

Ok, we all know I'm prone to idiocy, but that aside....

I have been hopping between FE and BE and I declared relationships in
the FE thinking that I was in the BE. The declarations now conflict. (I
finally realized that something was wrong because the "Enforce RI"
checkboxes were unavailable.)

So... The question is, how to fix it. The relationships are all correct
in the BE and a few are wrong in the FE. If I delete all the
relationships in the FE, will that fix it? If I do nothing, leaving
conflicting definitions, what will happen? What I wish is that within
the FE, I will simply "see" the relationships declared in the BE. (What
I also wish, but that is another story, is that this would work as it
does in ADP files, where you can have multiple diagrams, each devoted to
a subset of the data.)

Recommendations? Should I just kill all the relationships and the whole
diagram in the FE? 

TIA,
Arthur
