Hi Graham,

When you use the inspector to set a button icon,
you'll see it retains the [unique] ID of the image
that your icon really is. So try :
   set the icon of btn "myButton" to the id of \
       image "imageForIcon" of cd "MyIcons" of \
       stack "myStuff".

Hope this helped,

Jan Schenkel.
