Access97 and D4: linked tables invisible

Hallo!

I tried to get a connection to a client database (ACC97) containing linked
tables of a server database (ACC97, too). For D4 the client database is
known as ODBC-Source. I gave all rights to the user Administrator in both
the server  and the client database.

But the linked and only the linked tables keep invisible for Delphi's Object
Inspector. Why? Do you know a solution?

Thanx
Oliver
