changes to face customizations not saved

[Cliff Heller]

I recently upgraded to gnus emacs 21.3.1  from 20.x
I'm finding some of the highlighting during searches to be annoying.
so I explored customization options to turn it off.

However even after selecting "save customizations for future sesssions" 
which does write the following to my .emacs:
(custom-set-faces
  ;; custom-set-faces was added by Custom -- don't edit or cut/paste it!
  ;; Your init file should contain only one such instance.
 '(isearch ((t nil))))

Future sessions start up with the isearch face redefined as inverse
video.

any idea why this happens or how to prevent it?
