Ah, I see the issue.  I have a sub-doc with !TEX root = <whatever>, and
in the main file !TEX program  = pdflatex. However, the default engine
is pdfTeX.  So when I Ctrl+T in the sub-doc, TeXworks ignores the engine
spec. in the main file and tries to pdfTeX it.  Result: compilation fails.

I'd expect the engine spec in the main file to be respected here, I think.
