OK.  If you can repro it then I'm probably not helping
here.

I can't parse your last sentence.  Yes, I was looking
at a dired buffer.

I tested with this pretest build:

In GNU Emacs 26.0.90 (build 3, x86_64-w64-mingw32)
 of 2017-10-13 built on LAPHROAIG
Repository revision: 906224eba147bdfc0514090064e8e8f53160f1d4
Windowing system distributor 'Microsoft Corp.', version 6.1.7601

I just repeated the test with this other pretest build,
and I see the same things as before.

In GNU Emacs 26.0.90 (build 3, x86_64-w64-mingw32)
 of 2017-10-13 built on LAPHROAIG
Repository revision: 906224eba147bdfc0514090064e8e8f53160f1d4
Windowing system distributor 'Microsoft Corp.', version 6.1.7601

And I just repeated the test with Emacs 25.3.1,
and I see the same things I reported earlier.

In GNU Emacs 25.3.1 (x86_64-w64-mingw32)
 of 2017-09-26 built on LAPHROAIG
Windowing system distributor 'Microsoft Corp.', version 6.1.7601
Configured using:
 'configure --without-dbus --without-compress-install 'CFLAGS=-O2
 -static -g3' PKG_CONFIG_PATH=/mingw64/lib/pkgconfig'

HTH.

(I'm still guessing that you guys are using a more
recent Emacs 26 than these pretests, and that something
broke this since these pretest builds.)
