>While it talks of BROWSE windows, does anyone know if this bug can manifest itself with grids?
Browse is a grid. I.e. the browse command uses a grid internally to display its results.
I think this doesn't have much to do with grids per se, but with the buffers - the visible records in the child table somehow include the newly added records even if they shouldn't be visible. From what I understood that's what you'd see regardless of what you were using to display the records, as long as there's a parent and a child table... hmmm, does this assume an explicit Set Relation between them, and would the implicit relation set by relative expression set in the child grid have the same problem at all.
IOW, can't really say unless we know for sure that the problem existed with parent/child grids too.
