[plt-scheme] Autowrap in embedded text% snip

I just can't get this to work. :-/ I've made both editors instances of  
text:wide-snip%. I create a snip from the first editor using (new  
editior-snip% (editor theeditor)) and in the embedding editor tried   
(send editor add-tall-snip snip) which has no visible effect at all.

I've also tried

  (let ((snip (new-box-editor-snip 'ask ""))) ; my function that  
returns a snip
       (send editor insert snip)
       (send editor add-tall-snip snip))

This displays the embedded snip, but still no word wrapping or  
automatic resizing. Both editors are instances of text:wide-snip%

Is there an example somewhere that illustrates how add-wide-snip, add- 
tall-snip, and text:wide-snip% work?

Best regards,

Erich
