I had some problems reproducing your effect, but looking at the code the
handling of front and back color materials was not working right for
some cases. Now it looks like I would expect in the OpenGL log, can you
try it again? It's a little late for the Monday dailybuild in Germany,
but the VS.Net2003 noQT version should have the change already.
Hope it helps
