Hi, Helen,

   I reported this to Wolfram Research a while ago; the email I got back
said that it's a minor problem with the default settings in the init.m
file (unfortunately, I don't remember the exact way to change it, but
it's easy). Basically, if you put the option Lighting->False in the
ShadowPlot3D command, things should work as you want.

          Regards.
