Hi Dean, The first issue I haven't encountered yet. I can't really say where that's coming from. As for the second issue, that is a known glitch. Pymol (at least up to 0.99rc6) has a problem with multiple transparencies in ray-tracing. If you really need it, you can export the scene to povray, which will allow you to build complex scenes with multiple transparent objects. This may be the same issue as losing the shaded face between two boxes. There it may help to define each plane uniquely, rather than placing two boxes with the faces coinciding. Or you can try to add a little bit of space between the boxes. But I should add that I haven't tried these things yet.
By the way, I also bounce this mail the pymol user list, so that others may add their comments and/or can learn from it.
