You can also generate a rounded appearance with just one object.

1 - create a rounded rectangle graphic with the corner radii you want, say 30.
2 - name it "myMask"
3 - make it opaque & invisible
4 - set its rect to the card's rect
5 - set its geometry to scale with the window
6 - put this script in the card:

command maskMe
   import snapshot from grc "myMask"
   set the windowshape of this stack to the id of last image
   delete last image
end maskMe

True.

If you are willing to subject your users to some non-standard funkiness you can set the windowshape to 0 while they liveresize then use the above to make a rounded windowshape at whatever rect they end up with.
