font lock in emacs 21.3.50 using u-vm-color.el 2.3

[Allan Doyle]

Emacs version running as an App under Mac OS 10.2:
;; GNU Emacs 21.3.50.1 (powerpc-apple-darwin6.0) of 2002-09-17

VM version:
;; 7.07

u-vm-color.el:
;;  Time-stamp: "3. August 2002, 16:25:41 (ulf)"

The problem is that the summary buffer won't start out colored, nor
will it stay colored as new mail comes in. I have to manually run
font-lock-fontify-buffer. I changed too many things at once converting
from using emacs under XDarwin to using it as a Carbon app. (Guess I
should go back & test this in the old setup).

My .emacs contains:
(global-font-lock-mode t)
(setq font-lock-maximum-decoration t)
(if (fboundp 'turn-on-font-lock)
     (turn-on-font-lock))

My .vm contains:
(require 'u-vm-color)
(add-hook 'vm-summary-mode-hook 'u-vm-color-summary-mode)
(add-hook 'vm-select-message-hook 'u-vm-color-fontify-buffer)
(defadvice vm-decode-mime-message (after u-vm-color activate)
  (u-vm-color-fontify-buffer-even-more))

So, any ideas about how I can fix this?

Thanks,
