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. ------- Peter B. Steiger Cheyenne, WY
