Actually it does work, however you do not see the frame, because there
aren't any widgets inside it and you did not use the fill='both',
expand='yes' flags when you re-packed it, so it will end up with 1x1
pixels size. Here I can still see the blue pixel if I look closely right
under the "pack" button :)
