instance, I can kill PythonWin and all associated processes, and still
have no memory left!? I can't even start a shell window.
Windmill says: use Excell (or VB). It works fine for our
I've also tried to use calldll, but the IMLKIT dll delivered by
Windmill does not seem to work (16-bit?).
Any pointers are appreciated,
