Actually, I had already done that but thanks for the reply.

Alas, its all a little more complicated. I need to call winring-init on
the FIRST call to my ecb function but not on the others. In addition, if
I manually turn off ecb, it should not turn it back on when I move to a
c derivative.

at the mo I have:


(defun ecb-first ()
   (interactive)
   (ecb-activate)
   (ecb-winman-winring-enable-support)
   (winring-initialize)
)

(defun ecb-window-configuration ()
  (if(derived-mode-p 'c-mode)
    (ecb-activate) ;; **** call ecb-first on FIRST call??
;;    (ecb-deactivate);
    ))

(add-hook 'window-configuration-change-hook 'ecb-window-configuration)

The problem is the need to activate ecb before winring if you want
winring to support ecb. its all very messy and my elisp istn up to the
task :(
