The controls are not on a form, but appear to be. Anyway, I changed the property _SCREEN.Themes to .F., but it made absolutely no difference. When I added the following to the PRG screen's window definition, then this made a difference and I could then see the fields. I added COLOR RGB(,,,192,192,192) and commented out the previous color scheme. Frankly, @ SAYs and @ GETs stink!!!
