In the last few days nedit on those remote machines has been doing
spurious pastes. That is, whatever is currently in the X11 paste

do, I have not actually seen it happen, just found it when diff
indicated these odd insertions. My best guess is that these happen
while I am scrolling over these regions. Needless to say, this is
really not a good thing.
There have been only two changes recently.
1. I cleaned my mouse. 2. yum on 1/27/18 automatically installed on
those servers: xorg-x11-server-common-1.17.4-16.el6.centos.1.x86_64
To eliminate (1) the mouse was swapped with another one. Too soon to
know if that did anything.
I wonder if you aren't somehow accidentally clicking the middle mouse
button whilst scrolling?
That seems to be what caused it. Those errant pastes have not happened
again with the 2nd mouse. My best guess is that somehow putting the
mouse back together decreased the "click distance" on the scroll wheel,
so that now and then in the middle of a scroll motion there was also a
click. I would never see it when it happened because the scroll actions
on either side of the click would move it off the screen.

I seem to recall that before this if I highlighted a region in an
xterm window, then moved to another X11 application window, and

highlighted in the last window, nothing would paste. My memory may
be
faulty on this issue though, as I never paid a lot of attention to it
before it started misbehaving.
That wasn't right, but cut/paste is slightly different between "on the
console" and "over putty ssh tunnel with X11 Server on Windows".
On an XFCE4 ubuntu system console this is what happens:
I'm guessing this means a non-X terminal?
That is a regular X11 server, xorg 1.15.1. It just acts differently in
that it was possible to "select nothing".
Is there a standard way to clear this buffer?
I was going to suggest 'xsel -c' or 'xclip -i /dev/null', but that
doesn't work (in this case) for obscure reasons to do with cut
buffers...
Too bad. Sometimes I cut and paste hundreds of lines of text and those
are always a mistaken center click in an xterm away from hundreds of
bogus commands trying to run.
If you have any control of this issue a standard key stroke combination
to clear would be wonderful. Failing that, control-shift-center click
(or something like that) to paste and then clear would be nearly as
good.
For future issues, can I ask you to use the cygwin list, per [1]

I will try to remember that.
