What hardware are you using?  The ATI 95/96/97/9800 do not support polygon
anti-aliasing in hardwarer anymore.  They do support FSAA, and I have added this
capability to GEM, but it had only been tested on OSX.  If you are able to
compile GEM for Windows just change the define around the ARB_multisample code
in GemMan.cpp.

To make the spheres not transparent then add a [color 1 1 1 1] to the chain. 
The fourth argument is for alpha and will modify the transparency of the objects
in that chain.

ps - my mails don't always seem to make it to the list.  you can forward this
reply if it fails to reach the list.
