I suspect that the problems with Curves indicates a problem in the underlying architecture. Would it not be better if we had the concept of a Curve and a Curve Instance. The former holds the vectors of the Curve, while the latter holds the properties (color, line style, etc) and knows how to draw a Curve. This way the user can have the same Curve with different properties. The Curve could hold default properties which would be used when a Curve Instance is created, essentially acting as sticky properties. There could also be the conpect of a copy of a Curve Instance in which modifying one Curve Instance would also impact the copies.

In the interim, I would propose that we simply cycle through the Curves. We could "mark" Curves as treated (as Nicolas suggests) but this represents more code and it doesn't really matter if we set the Curve properties based on the first or the last instance that we meet (which would be essentially random anyway).

Incidentally, I'd like to change the two list boxes around in the "Monochrome Print Configuration" as the Available and Selected are opposite to the way they work in the Plot Dialog Content tab working on Curves.
