Try changing

Try changing
x-selection-strict-motif-ownership
to nil. Seems like this should be the default.
Thanks!
I just set it to nil, but I won't be able to try it out for an hour or
two as my remote system is currently running Windows and I can't boot
up FreeBSD for a few minutes. I'm suspicious as the FreeBSD system is
NOT running Motif. It's running Enlightenment.

Notes:
1. It doesn't matter whether you're using Motif. The name comes from
the fact that the "clipboard" functionality was provided by Motif
rather than X itself. Some programs (e.g. XEmacs, xterm) implement the
"Motif clipboard" protocol themselves, without requiring Motif.
2. The name is misleading; the variable controls the behaviour of the
clipboard, not the selection.
3. Setting it to nil has undesirable side effects, i.e. you can no
longer copy from XEmacs to another application using the clipboard.
4. A better solution is to set interprogram-cut-function and
interprogram-paste-function to nil. That way, kill and yank operations
(C-w, M-w, C-y etc) are purely internal operations, and don't suffer
the overhead of doing lots of X protocol. You can still copy to and
paste from the clipboard using C-insert (copy-primary-selection) and
Sh-insert (yank-clipboard-selection)

Bingo! It's MUCH better, now. But the description of the variable
leaves me very confused. Does this mean that I do want it true when
the display is Motif? Or when the display is remote and Motif? I assume
that it's a good thing in some case.
In most cases the xemacs is running on a system with Motif. But the
display is often (but not always) a non-Motif system when it's not
local. In this case the local system has Motif (but that should not
matter that I can see) and the remote system is FreeBSD running
Enlightenment as the WM.

The term "the display is Motif" doesn't have any meaning.
Basically, you might want it set to nil if the display is remote. But
I would recommend using the interprogram-*-function variables instead.

The term "the display is Motif" doesn't have any meaning.
Let me re-phrase. I built XEmacs on a Tru64 UNIX system with Motif, so
the Motif support is built for dialog boxes. The system I display to
lacks a Motif library.
Basically, you might want it set to nil if the display is remote.
But
I would recommend using the interprogram-*-function variables instead.
The down-side is that x-selection-strict-motif-ownership is
interactive and very easy to change. The interprogram- variables
are not, so I need to do some defining in my init.el to make it
reasonably easy to turn them off.
