You need to call some kind of "clean up" method to remove the internal reference in your BO.oDataLayer. You can't do it in the BO.Destroy, since that occurs AFTER the Form.Destroy, but you could put it in the Form.Destroy. You could also use BINDEVENT to the form Destroy to call a method on your BO object to do the clean up itself.
