I'm re-sending this since the mail server rejected the .zip attachment,
it seems:

Hmm, okay.  /usr/bin and /bin and /usrX11R6/bin are all in my PATH. 
The error message is:

xinit:  No such file or directory (errno 2):  no program named "/usr/X11R6/bin/xterm" in PATH

Since there is no /usr/X11R6/bin/xterm (only a /usr/bin/xterm), I
suppose it's correct.  I haven't been able to find what it is that's
referencing the absolute path to the old location for xterm.

(It still seems strange to me that it moved to /usr/bin.)

No, if it was asking for /usr/bin/xterm it would have been okay. 
Something is asking for /usr/X11R6/bin/xterm.

I don't think so.  FWIW, here is my full and ugly PATH, wrapped for
easy reading but no other changes:

Apart from some classically-stupid repetitions, and one complete stupid
and excessive repetition I didn't expect (mport), it seems functional
if inefficient.

I definitely have a custom .xinitrc file.  In fact part of our site
post-install process was to create a default one, since initially
Cygwin's XFree didn't include it.  I hadn't realised it was colliding
with one from Cygwin.  Our standard site post-install creates the
~/.xinitrc.  Sounds like I'd better try to back that out.

How much does Cygwin's XFree depend on the (traditionally)
user-controlled .xinitrc file, to work properly?  Does it also depend
on specific Cygwin things in ~/.Xresources?

I'll zip up and attach the files, anyway.  I've included an XWin.log
from a failure when started with -multiwindow.

Yep, I recognised the behaviour.

Are there any docs on -multiwindow and using the Windows desktop as
your window manager?

Ah, yes, I knew there were some new startup scripts but I couldn't
remember what they were.  I'm still using the version of /startx.bat
that I modified, and pointed to from a desktop shortcut I've set up.

>  Lets have you try these things first and see where it goes.

Absolutely.  Thanks, Harold.

I tried startxwin.sh without a lot of joy.  I can't see where it gets
its starting set of windows, and I can't see how to start up any
windows conveniently either.  (Currently it has -multiwindow and
-clipboard hardwired in - it doesn't seem to do any argument
processing.)

I may change that and send you a revised one, if you'd be interested.

Perhaps my question is, why would anyone choose to run multiwindow
using the Windows desktop?  There seems to be no easy way to start X
applications, except presumably from the command line.

It doesn't seem to use .xinitrc how I'd expect.  Sure, if I add an
"exec wmaker" then it all fails because it thinks a window manager (the
Windows desktop) is running, and bails out.  But if instead I add an
xmessage "Quit X" at the end instead, that never appears.  I just end
up with the "console window" with yellow text on black background, and
an icon in the Windows tray, that I can use to exit X or unhide the
root window.

If I unhide the root window, then the X cursor disappears.  Nor can you
call up a root menu, since I suppose Windows doesn't understand that.
And I know of no way to get a root menu in the Windows + multiwindow
"environment" or mode.

Also, as I said, if I unhide the root window in this mode you can't
exit from X.  You can request to do so, but it doesn't exit until you
rehide the root window.  You can also exit from the taskbar icon if you
have the root window hidden, but not if the root window is displayed.

Hope this makes some sense, and/or is of some use!

Oh: given that I had my own .xinitrc file, how can I get a copy of the
one Cygwin would have installed?  Move it aside and re-run setup?

# are relative to the left (or top) if they start with a `+', and
# relative to the right (or bottom) if they start with a `-'.
# So 80x24+0-0 means 80 cols, 24 lines, 0 from the left edge of the screen,

# -fn 9x15 means choose the 9x15 (in pixels) font. And 9x15bold is just that.
