>>The result is no rows shown in the grid. (Not the empty grid you'd get without Safe Select). If I click onto _SCREEN and then back on the form, the grid fills in.
IME this infuriating and time-wasting "feature" usually improves if you formally setfocus() to a control away from the grid before repopulating/refreshing it. I don't believe that a toolbar button will suffice; try thisform.btnDummy at -100,-100 whose only purpose is to receive focus. Bring focus back to the grid afterwards if needed.
"... They ne'er cared for us
yet: suffer us to famish, and their store-houses
crammed with grain; make edicts for usury, to
support usurers; repeal daily any wholesome act
established against the rich, and provide more
piercing statutes daily, to chain up and restrain
the poor. If the wars eat us not up, they will; and
there's all the love they bear us."
-- Shakespeare: Coriolanus, Act 1, scene 1
