Usually, I did not have problems too, but, you know, twice for the last 3 years (i.e. VFP life scope) I really got this miraculous corruption when grid cell gets blank while getting focus and restores data (and possibly deleting it if grid is not read-only) after losing focus. Both times I had to rebuild grid from scratch. As I mentioned, I don't mean that re-building is not possible or bad way. I just said that another approach is possible and sometimes makes sense.
