Drupal : désactiver / activer Tinymce avec le bouton : “disable rich-text”

De base le bouton qui permet de désactiver / activer tinymce ne fonctionne pas !
Afin de rendre fonctionnel le bouton  de tinymce “disable rich text”, il faut modifier le fichier tinymce.module :

--- tinymce.module	2008-04-08 09:53:01.000000000 -0400
+++ tinymce.fixed.module	2008-04-08 09:46:29.000000000 -0400
