This may be the top-level base sizing bug that Kevin refers
to, but it might also be (alas!) programmer error. :-)

The "4 pixels in each direction" part makes me suspicious.
Sounds to me like what you want to be doing is resizing
your draw widget *canvas*, not the whole draw widget. I
would be using the keywords Draw_XSize and Draw_YSize on
the Widget_Control command above. Try that and see if it
helps.

Cheers,

David
