This is interesting, since I have exactly the opposite problem from
Patrick. My XFWINDOW procedure, when started on a color-starved 8-bit
display, *doesn't* flash the colors. The window does have a draw
widget and enables tracking events.

The end result is that the widget gets stuck with the same ridiculous
color table no matter where I have the mouse cursor. [ Of course if I
have enough colors to begin with everything is fine. ]

Pray, what do tracking events and color map flashing have in common?
