Ahhh, thanks very much. My problem was with draw widgets not
labels, but surrounding the change with UPDATE=0/1 ie.
WIDGET_CONTROL,info.drawID,UPDATE=0
WIDGET_CONTROL,info.drawID,XSIZE=nx,YSIZE=ny
WIDGET_CONTROL,info.drawID,UPDATE=1
works just fine. If you don't mind a bit of flicker,
then this also does the trick
WIDGET_CONTROL,info.drawID,XSIZE=nx,YSIZE=ny,UPDATE=1

Whoops! Sorry. Brian's already tried this. Have to learn
to read the WHOLE message before I get all excited. :-)
Abashed in Colorado.

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
