I would be interested to know why some programs will not run in a windows DOS box, they detect the presence of windows and require that the computer be restarted in DOS mode. There are very few such programs, as they obviously have the huge drawback of requiring a restart in DOS mode, but I have seen one or two that do.

These aren't new programs, the two I have encountered (a tabulation app and a game called cannon fodder) came out about six or seven years ago, but they refused to work under windows. Does anyone know what pure DOS gives you that win DOS does not?
