Long ago (X11R3? - I don't recall) there was a convention for loading
per session values for things like appdefaults and Xmodmap.  Or maybe
that convention only existed on the particular systems I was using in
those days.  Regardless, the evolution of x11 implementations and the
proliferation of system configurations seems to have destoyed any
consensus that may have previously existed. We distribute the Resources
file so that you can see what can be changed.  It's up to you or your
distribution whether to configure the system so that these changes are
always in effect.

No idea. I've never had it turned on to the best of my knowledge :-)

Looking at the code in gplt_x11.c, I see that it causes the following
request to be issued:
XSetSelectionOwner(dpy, EXPORT_SELECTION, plot->window, CurrentTime);
But that by itself shouldn't do much of anything other than to allow
you to make a subsequent selection in the plot window.  I don't see why
it would erase your paste buffer or prevent another window from
regaining focus and reclaiming ownership of the selection token.
