One possibility is that you forgot to specify :COLOR-P T when you created
the window. (I know, I know, I get burned by this myself a lot too. We'll
change the default for :COLOR-P from nil to t in a future release). 

You can make sure this doesn't happen by adding this to your window's defclass:

(defclass my-window (window)
  (... other slots ...)
  (:default-initargs :color-p t))

I've written a pretty simple example file, available in our user library
as cambridge.apple.com:/pub/MCL2/contrib/window-example.lisp.
