A feature, I think. We don't want anyone doing anything "irregular". :-)
Since I've never run into this, I'm going to guess that it comes
about by creating a unrealized base widget in order to add the
system colors to the list of colors the program knows about. Maybe
X windows doesn't allow you to do that. I'd comment out that big
IF statement, starting on line 1087, and see if that doesn't fix
the problem.
Let me know. :-)
Cheers,
David
