This definitely sounds like the problem I've been describing with GV warning messages causing the Runtime call never to return. Are you using the 3.0-alpha/SVN version of IsaViz, or a pre-compiled version ? If you'e using the latest version from SVN, one easy fix is to: - comment out line 417 in src/org/w3c/IsaViz/RDFLoader.java - uncomment line 416 in src/org/w3c/IsaViz/RDFLoader.java - compile again with "ant isvjar" This will ask GraphViz to be silent and should solve the Runtime call never returning issue. If you;re not using the latest SVN version, I can build such a version of IsaViz, send it to you so that you can test it (I am not able to reproduce the problem), and then I'll release a new version.
