OH. MY. GOD. If I understand the problem and solution (which I marginally do), and Win9x vs. WinNT/XP (which nobody really does), this ***~2.66x*** speedup should be even greater on NT/XP. I'm giddy with anticipation over what this might do to configure times etc. This may be the coolest thing since sliced time. -- Gary R. Van Sickle Brewer.
