I’m working with nurbs evaluators for curves and surfaces, and they work fine. (gluBeginCurve/Surface, gluNurbsCurve/Surface, gluEndCurveSurface)

Then, I have changed the glu32.dll version 1.2.2 coming with W2K SP3 to glu32.dll 1.3 (getting it from internet¿¿??) and now the surface evaluators follow working well, but curve evaluator are not working.

I have tried with the same curve object to avoid errors in the curve definition, and the result is the same.

Can somebody help me?
