Hi Dan-

>However, if I download the Windows version of IDV and start it up

This indicates that you don't have Java 3D installed on the
version of Java that is being used.  The Web Start version 
installs Java 3D automatically.  

I'd recommend using the Java Virtual Machine (JVM) that comes
with the InstallAnywhere installer which has Java 3D included.
Then use the runIDV.bat script to start up the IDV which uses
the java in the jre/bin directory.

The InstallAnywhere version of IDV does not know about the java
resources that the Web Start version uses.
