Fred,
Another option would have been to open the master table again under a new alias in the child form and set the relation as you wanted it.

Master -> Child -> Master1

Because you were using the default datasession setting for the forms, no new datasession was created and both forms lived in the same session. As such, when you opened the child form, it found that both tables already existed and it didn't have to open them. But it did have to set a new relation. Because relations are added Additive, it created your cyclic relation. And as you found using separate datasessions per form corrected this problem.
