Ah, I see.

Yes, well, ITTVIS assumes you will be running a crippled
graphics card. Try these two commands:

IDL> Device, Decomposed=0
IDL> d_plot2d

This is really an inexcusable programming error for a demo
system, in my opinion. Please don't use this code as an
example of how IDL programs are suppose to be written. You
can find MUCH better IDL code elsewhere on the Internet. :-)

Cheers,

David
