Vidar,

What is teh currently selecvted work area when you are navigating your parent grid? If it is not the parent table, then all relations from that table are suspended.

You may have better luck dumping the relationships and using the child grids' LinkMaster, RelationalExpr, and ChildOrder properties to make the relations.
