If you intend to stay with FoxPro 2.0, and intend to use the Extended Edition, there are strong reasons to stick with the Win9x platform - there are fewer conflicts between the Win9x memory management and the older DOS Extender used by FP 2.0 than there would be with NT. Regardless of which platform you pick, you'll have to be careful to set up the memory management environment for FP 2.0 to avoid problems with the various Win32 memory managers.

FPDOS 2.0 Extended does not understand XMS or VCPI memory, and will need you to make EMS memory available through the OS. If you make >16MB of EMS and conventional memory available, it's likely to fall down and go boom at odd moments, too. If you can stick with Standard Edition, there are far fewer issues with memory managers in Win32 environments. I wouldn't want to guess what new and exciting vistas will be opened if you try to bring up 2.0 Extended under Win2K or Millenium when they ship.
