Ken,

this is a Java-related problem and editing isaviz.cfg is not going to 
change anything (this file only holds user preferences).

The problem is that your JVM does not find class org.w3c.IsaViz.Editor 
which should be in the JAR archive called isaviz.jar
This is the first time this problem is reported.

 From the content of your coomand line, everything seems to be fine.
Can you give me the output of the following command, run from the isaviz 
directory:  "java -version"


And also, can you list the content (with details like file sizes) of the 
IsaViz/lib/ directory?


What you could try is to put full paths in your classpath (e.g. 
C:\apps\IsaViz\lib\isaviz.jar;C:\apps\IsaViz\lib\vtm.jar;....)

If this does not work, you could also set an environment variable called 
CLASSPATH holding the same value, and then call "java 
org.w3c.IsaViz.Editor"  directly.
