Hmm.  Looking back at my notes, I didn't try expose events, but I
*did* try tracking events, which should be the appropriate thing.
Tracking events are generated whenever the mouse enters or leaves the
widget, while expose events only happen when a part of the window is
exposed and needs to be redrawn.  

The point remains: IDL doesn't switch the color tables when entering
draw widgets.  LOADCT may load a new color table internally into IDL,
but it never becomes active on the screen.
