It seems that your interface is complicated, so it is hard to come up with something you did not try yet. There is one common thing that can hurt grids, they don't like switching/zapping recordsources when focus is on them, e.g. it may happen inadvertently if grid is the first control in page tab order and you do something in page.activate. If it is not the case in your pageframe then, maybe, you could just try to delete the grid altogether and create new one from scratch, and then test it methodically until lostfocus will stop to react.

>>>>If you do entry then focus is obviously on textbox. Maybe you have code in some other events, e.g. Interactive or ProgrammaticChange that moves focus out? I would suggest you to check when Textbox.LostFocus event gets triggered during the entry process. Btw, placing valiadation code there, i.e. using LostFocus instead of Valid would be quite consistent too.
