Excellent and well thought-out response. Thank You
Much food for thought which I will now ponder. Will report back to this
list when I figure out a "fix"

The "blooming" occurs immediately after either the Shutdown or Restart
command is selected from the menu. It does NOT occur when the log out
choice is selected.  It DOES "balloon" briefly during selection of
either the Suspend or Hibernate option. It is mercifully short when
doing a Suspend or Hibernate so I can live with that!
