Not always.   I've been experiencing  this annoying for some  time.  I
think the OP  has got the same problem that  I encounter.  Select text
in xterm,  and C-y  in Emacs (or  middle-click) while seeing  the text
still highlighted in xterm.  Emacs  pastes from the king-ring, not the
selection.  With the text  still highlighted in xterm, middle-click on
other apps and they all get the highlighted text from the xterm.

Worse yet,  this behaviour  is quite random  (to me).   Sometimes, C-y
does  paste   from  a  selection  (form   whatever  other  X-clients).
Sometimes, it  just pastes  from the kill-ring,  as if there  were not
selections  at all.  I  still haven't  figured out  the rules  of when
Emacs behaves one way and when the other.  So, to me it's "random".

I  do understand  how  the  X selection  mechanism  works.  I've  even
programmed it in  C/Xlib.  That does not stop  Emacs from misbehaving,
though.
