I am working with an enhanced version of the NorthWinds DB that came with a
book from Microsoft Press.  It does everything I need to do for a project at
work.  However, I cannot delete the existing records in order to adapt it
for my use.  I've used the Access utility to copy database structure to
clone the database using  the "Definition Only" option, but it did not work.
(The utility did successfully clone another Acess database, so I know it
works.)  Apparently, there is some addiitonal protection that prevents the
removal of its records.

When I try to remove the relationship between two tables I get an error
message that I can't delete relationships from "linked tables" from an
"inherited" database.

When I open a table in Design View I get a warning that the table structure
cannot be modified.

If I edit a relationship between two tables I can see that referential
integrity is checked, but it is greyed out, so I can't change it.

This database does everything I need it to do.  All I need is to purge the
exisitng data and my project is done.  Question:  Does anyone know how to
hack into such a database so that I can clone the structure or delete the
existing records?
