To be honest I didn't know you could save to a ps file. 
You are probably better off capturing the display as an
image (.e.g, png) and then bringing it into word, etc.,
for final formatting.

Yes, you can edit it. I am attaching the dri xml file. Just add a
elev="elevation in meters" to each entry. Mail this back to
me and I will rebuild the jar file if you want.  If you have a java
jdk installed you can do:
jar -xvf trex.jar
look for the dri.xml file in:
ucar/unidata/apps/trex/data/sensors/dri.xml
edit it. then create the new plugin:
jar -cvf trex.jar ucar

It depend on what data servers you are accessing. At start up the IDV
fetches a resource xml file from our web server (port 80).
The Thredds data server usually is on  port 8080. The ADDE servers
are accessed via  port 112.

That's a bad error. The JVM core dumped. I get that occasionally on my Linux 
box.
Unfortunately I don't have any solutions to offer.
