No, I haven't. I have a main table which I will call tblMain for purposes of explanation. tblMain contains several foreign keys which are the primary keys in linked tables. When I open the relationship window, tbl Main is duplicated with a link to itself and to two of the linked tables. There are more than 20 tables, but only two of the "lookup" tables are causing a problem. I don't have a lookup query in the field of the tbl main so I don't know what the problem is. It has slowed the query process to a snail's pace!
