font-locking..fails to set certain strings to bold/italics

["William Payne" <mikas_n_o_s_p_a_m_493@student.liu.se>]

Hello, in my .emacs-file I have (among other things) this block of
"statements":

(custom-set-variables)
(custom-set-faces
 '(font-lock-comment-face ((t (:italic t :foreground "Green"))))
 '(font-lock-reference-face ((((class color) (background light))
(:foreground "LightGreen"))))
 '(font-lock-string-face ((t (:italic t :foreground "Gray"))))
 '(font-lock-keyword-face ((t (:bold t :foreground "Cyan"))))
 '(font-lock-constant-face ((t (:foreground "Yellow"))))
 '(font-lock-type-face ((t (:bold t :foreground "White"))))
 '(font-lock-variable-name-face ((t (:foreground "Yellow"))))
 '(font-lock-function-name-face ((t (:foreground "Cyan"))))
 '(font-lock-builtin-face ((t (:bold t :foreground "LightGreen")))))

My problem is that it only sets the color, it fails to set certain types of
"strings" to bold/italic as it should. I have been making a lot of changes
lately to my .emacs-file but I haven't touched this part and it used to
work. Has it to do with me adding a default font? I do that like this:

(if (eq window-system 'w32)
    (progn
      (add-to-list 'load-path "c:/emacs-21.3/cc-mode-5.30.8")
      (set-default-font
"-raster-Courier-normal-r-normal-normal-16-120-96-96-c-*-iso8859-1")
      (w32-send-sys-command ?\xf030) ; Start as maximized. Or use $
emacs --fullscreen
      ))

Please help me! I really would like to know why it stopped working.
