<P><FONT SIZE=2>Sorry for what is likely a stupid question, but Herbert, when I latex the file you sent I get lots of errors, the first being<BR>
! LaTeX Error: Unknown option `dvipsnames' for package `pstricks'.<BR>
Then it sayes \definecolor is an Undefined control sequence.<BR>
Then with the colors all undefined they get spit out as text on the diagram, but the phase diagram itself looks OK.<BR>
<BR>
So I guess I'm missing something that gives me the dvipsnames option for pstricks?<BR>
<BR>
I'm on a Fedora Core 2 installation of Linux.<BR>
<BR>
Though I'm not working on any such thing right now, I don't like when I can't compile the examples (generously) given on the list. Any help appreciated.<BR>
