I guess that you feel that the software is running too fast on that
computer? Odd to think that way but I guess that some people prefer to get
a cup of coffee between operations.
I'd stay away from windoz when running a good DOS program as the way that
windoz of any variety runs tends to slow a computer way down when dealing
with anything to do with the outside world of the processor. Math and
logical work isn't affected by windoz but unless there is a lot of that, you
will note a real slowdown of the program from the DOS version.
