[AccessD] Link child / master field fails in subsubform

I have a db where the subform pulls the correct records using ling child /
master field properties, but the subsub form fails to follow the subform,
i.e. it pulls a set associated with the parent form but not associated with
the first subform.

Agency / contract / assignment.  As I move through agency records I see the
contract change.  I also see the assignment change, but as I move through
the contracts the assignments don't change.

I have seen this before, and worked around it by just replacing the link
properties with query filters in the subform.

Has anyone seen a bug fix for this?
