Hi, Ben,
FWIW, I always set the data source of a grid to a DataTable. Is objDatabase.DataSets(Me.FormID) a DS or a DT? (I realize you're setting the DataMember).
Other than that, I don't have an immediate clue. (You might want to try a form refresh, though I'd be really surprised if that did it). Sorry I can't think of anything else.
