That is exactly the problem.  On NT/XP systems, there is a third-party
program called TAMEDOS which intercepts the busy loops and does
something so that the CPU is free but the application does not slow
down.  I have no idea how it works.  Clipper was written in the early
80's when there was no problem for a program to take over the CPU... I
know at least one of the loops is a constant keyboard poll: "Is anyone
pressing a key yet?  What about now?  What about now?" hundreds of times
a second.
