I don't know why, but I've noticed that some textures (even some of the Bryce5 presets) have refraction set higher than 100, even though they have 0 transparency. When I change the refraction to 0, it seems to have no effect on the appearance of the texture in rendering (although it does speed it up, indicating perhaps that the higher refraction setting was doing something, I just don't know what).

This is not my "second childhood". I'm not finished with the first one yet.
