	PROBLEM:  How to have more than one configuration each with
	its own menu pane and command table.

I think you will also need to (SETF (CLIM:FRAME-COMMAND-TABLE ..) ..)
to get things copacetic.

    The following works for me:

    (define-command-table primary)

    (define-command (com-red :command-table primary :menu t) ()
      (echo-command *application-frame* "Red"))

    (define-command (com-blue :command-table primary :menu t) ()
      (echo-command *application-frame* "Blue"))

    (define-command (com-green :command-table primary :menu t) ()
      (echo-command *application-frame* "Green"))

    (define-command-table secondary)

    (define-command (com-yellow :command-table secondary :menu t) ()
      (echo-command *application-frame* "Yellow"))

    (define-command (com-cyan :command-table secondary :menu t) ()
      (echo-command *application-frame* "Cyan"))

    (define-command (com-magenta :command-table secondary :menu t) ()
      (echo-command *application-frame* "Magenta"))

    (clim:define-application-frame multi-menu ()
	()
      (:command-table (t :inherit-from (primary secondary)))
      (:panes ((display :application)
	       (own-menu :command-menu)
	       (primary-menu :command-menu

	       (secondary-menu :command-menu
			       :display-function '(clim:display-command-menu :command-table secondary))))
      (:layout ((primary
		 (:column 1

		  (:row 1/6 (primary-menu :compute) (own-menu :rest))))
		(secondary
		  (:column 1
		   (display :rest)
		   (:row 1/6 (secondary-menu :compute) (own-menu :rest)))))))

    (define-multi-menu-command (com-exit-multi-menu :menu "Exit") ()
      (frame-exit *application-frame*))

    (defmethod echo-command ((frame multi-menu) string)
      (let ((stream (get-frame-pane frame 'display)))
	(format stream "~%The ~A command." string)))

    (define-multi-menu-command (switch-configurations :menu "Switch") ()
      (let ((new-config (case (frame-current-layout *application-frame*)
			  (primary 'secondary)
			  (secondary 'primary))))
	(set-frame-layout *application-frame* new-config)))
