Background Color in dialog-items

[welch@aristotle.ils.nwu.edu (John Welch)]

Help!    
	I can't get radio-button-dialog-items or check-box-dialog-items to 
display in any background color other than white. I have no problem changing
the text or frame colors of these items but the background stays stubbornly
white. If there is a patch for this bug I would be very gratefull to know 
where I can get it. Below I have included an example to show that I am not
hallucinating:

(setf test (make-instance 'window :color-p t ))

(add-subviews test
                (make-dialog-item 
                 'radio-button-dialog-item
                 #@(10 10)
                 #@(100 20)
                 "Test"
                 nil))

(add-subviews test
                (make-dialog-item 
                 'radio-button-dialog-item
                 #@(10 50)
                 #@(100 20)
                 "Test"
                 nil))
(set-back-color test *green-color*)

(set-part-color (first (subviews test)) :text *red-color*)
(set-part-color (first (subviews test)) :frame *red-color*)
;;; Now for the part that does not work

(set-part-color (first (subviews test)) :body *green-color*)
