[racket] Embedding a GUI editor into Slideshows

I tried the following, but the new frame is not shown on top of the slide (I
need to alt-tab to see it):

#lang slideshow
(require racket/gui)

(define frame (new frame% [label "Example"]))

(define msg (new message% [parent frame]
                 [label "No events so far..."]))

(new button% [parent frame]
     [label "Click Me"]
     (callback (λ (button event)
                 (send msg set-label "Button click"))))

 #:title "Test"
 (clickback (hyperlinkize (t "Hello"))
            (λ () (send frame show #t))))
