Ok, I misunderstood you. You stated that grids 'force' table buffering, when really they just default to table buffering, and you can change this by setting the cursor's buffering property.

VFP defaults to using row buffering with tables bound to all controls except Grids, which it defaults to table buffering. Look in VFP 5 or 6 Help for BufferMode you'll see what I'm talking about.
