Is she using the same database file (the actual Design Master) that you are?
Or did you make a copy of it and give that to her?  Making a copy of the
Design Master changes that copy to a replica.

A Back End database design master *ONLY* contains tables. The Front End
application holds the Table links, Forms, Reports, Macros, Pages and
Modules.

One more thing, only the database administrator should be changing the
Design Master tables.

I made a replica and design master on a network.  I can
modify the design master, but other users cannot modify
the design master (this is a user that previously could
modify reports in the original database before I created
the design master & replica).  She gets a message in the
design master "can't modify the design of "XXX" as a
replica".  What could be causing this?  Is there some
reason that only the person who created the design master
can modify reports, etc.?  Thanks!
