*That's* why it is. For years I've launched my command shells from one
of various shortcut-key utils and I *never* tumbled to the fact that
that meant my cmd shell was running inside that util's process and so
didn't inherit env var changes. Thanks so much.

I have used Launchy, as a matter of fact, but for some reason it never
really clicked for me -- maybe I use a small enough range of programs
normally -- so I ended up uninstalling it. I agree it did what it did
very well, though.
