Relationships screen - we had a case recently where the relationships were broken. Data was lost, but recovered. The relationships have referential integrity. How can the links disappear? Is there any way to lock down or hide that screen?
I have never had Relationships *break* without someone removing a table (this could happen if using Make Table queries) and/or going into the Relationship window and *breaking* them. Are you shure they are broken? Did you try clicking the *Show All Relationships* button just to see if they are not showing?
