Thanks Coridon.
It is eluding me at the moment.  I had it doing so again once I put a light
source in with your script but using the text object I was finding it happen
with before.  Not only text objects though, I first noticed it when I
checked on making a sphere and box CSG transparent as a different test.
Wish I had grabbed a screen shot of the rather wildly wrong look to it when
I had the chance.  Trying with your simpler scene and that box it wouldn't
make itself shown, and now I can only get a slight yellowing of the text
object I was using too.
I know Thorsten keeps saying this stuff can't change on it's own but this
wouldn't be the first time such an experience has occured.
Anyway, I'll get back with anything I have once it shows itself again.
