Go up one level in this thread


One thing to watch out for is that Win 98 and NT both normally give
a priority boost to the window that has the focus. You can adjust the
degree of boost (and if you do a lot of benchmarking you might want
to set it to zero). If you don't change it, you want to be sure that
your program has the focus or runs in the windows that has it.
