Still using VFP9 to this day. Our application originated in ~1986 in dBase II, then we switched to FoxBase, then the various version of FoxPro. Currently in VFP 9. But, we still have to invoke Foxpro for DOS 2.5 (in DosBox) to edit some report layouts, because they were created in the DOS version in the 90s, and the automatic tool to 'transport' them to new versions crashes hard for reasons we were never able to figure out.
