On the other hand, this seems to be a platform and/or system specific
issue.  This was the behavior I was seeing on my Win98 system at home.  I
am not seeing the same problem on my Win2000 system at work.  Oh well...
that's windows for ya.

It may be influenced by the video driver as well. But in any case, I'll
change win32lib. As a "special", I just might include a "htmlcolor.ew" file
with the next release. This gives names and RGB values for each of the
defined HTML colors.
