Thanks for pointing that out.

That may be, but I need this to work when cygwin is not running.  When cygwin
is not running, I don't have X available (unless I do a whole second setup of
X, only for this use - I'm not inclined to do that).

In the External Editor add-on, if I set the text editor to be:

"C:\Program Files\Emacs\bin\emacs.exe" --no-splash --file

then things work, though I get the annoying console window.

If I use this:

"C:\Program Files\Emacs\bin\runemacs.exe" --no-splash --file

then emacs pops up, but says the email message is a new file.

However, I think we're making progress on diagnosing this.  When I
looked very closely at the mode line in emacs, I could see the underscores
were actually there.  The two cases start up pointing to the same file
name in the same folder.  In the runemacs case, however, the file is
not present by the time emacs pops up.  Here is my theory.  runemacs
returns immediately after starting emacs.  Thunderbird sees that
return, reads back in the file it wrote, and deletes the file.  Then
emacs tries to open the file and does not see it.

If this theory is right, what I need / desire is for runemacs to wait
for the emacs child.  But AFAICT runemacs is not designed to do this.
I end up desiring a case not provided for, and hence probably need to
just live with the annoying pop up console window.

At least I think we have an explanation.  Still, it would be nice if
I could tell runemacs to wait ...

I appreciate your help with this.
