[TYPO3-RTE] Launching external CSS

[Xatucans]

Hi, I've created an external css document with my own classes to display in
rteHtml area. I´ve written this code in the TSconfig of my root page:

#Configuración del RTE#
 RTE.config.tt_content.bodytext.showButtons = bold, italic, underline, left,
center, right, justifyfull, orderedlist, unorderedlist, outdent, indent,
link, image, table, removeformat, copy, cut, paste, undo, redo,
showhelp,chMode

 #CSS#
  RTE.default {
   contentCSS = fileadmin/css/pags-interiores.css
   enableWordClean = 1
   useCSS = 0
   showTagFreeClasses = 1
   classesCharacter = lista,ladillo,subladillo,negrita
   classesAnchor = lista,ladillo,subladillo,negrita
   proc.allowedClasses = lista,ladillo,subladillo,negrita
  }

  RTE.config.tt_content.bodytext.proc.allowedClasses <
  RTE.default.proc.allowedClasses


and I´ve linked my css style sheet (pags-interiores.css) in all pages, but I
can only see my own classes in paragraph menu of my rteHmle area, the Text
menu is inactive and I would like to display my new classes in both menus.
Can anybody tell must I do? Thanks
