Hi Bill,

the OOP solution is (best if native on VFP ).

Fill Parent ( or add formParent ) property of form with parent form object.
Then:

thisform.FormParent

implement WPARENT() on OOP and remove the ambiguity on window name.

Much useful one would be WCHILD() on OOP:

thisform.FormChildCount
and 
thisform.FormChilds collection

......

I have implement this ( window native menu can to be defined only on Top Form ).
