Hi All, When I create a simple draw widget, the background color
defaults to black. How do I change that to a light grey? Thanks for
your help! Cindy

I know. But does it help when you do? ERASE sets the background color
to the default color (=!P.BACKGROUND) or to the one you specify (which
is an 8bit color index or a 24bit color value, depending on the
DECOMPOSED state of your device).
