Yep, the eternal optimist. Still hoping for world peace. ;-)

I was afraid of that. The only reason I pursued it this far was that I
did not write the .bat files; my company did, and I came across this

It would appear to me on the face of things that _spawnve would get
around the quoting issues entirely.
