No, I'm on MS Windows - a native Emacs build. I do have Cygwin installed
also, but the Emacs I use is not a Cygwin Emacs.

I agree; the problem is not Emacs. I just don't know how to find the problem
(and solution). (The same Emacs builds (20, 22) work fine on the old laptop,
which is supposedly almost identical, so Emacs is not the culprit.) I'm
hoping someone here might have run into this or otherwise has an idea.
