Equinox works fine under Solaris but fails under NT with java.lang.IllegalStateException: wakeup0n must be called from initialize or processStimulus at javac.media.j3d.Behavior.wakeup0n(Behavior.java:98) at visad.java3d.RemoveBehaviorJ3D.setWakeup(RemoveBehaviorJ3D.java:90) ... The 3-D surface appears but the green and yellow tracking dots do not (CellImpl). I'm using Java3D beta 1, JDK 1.2 beta 4, and the latest VisAD distribution as of today on both machines. Equinox is available at http://www.wizards.dupont.com/Equinox. Note both NT and Solaris versions of Equinox worked fine under JDK 1.2 beta 4 and Java 3D Alpha. Unfortunately I cannot locate a copy of the windows version of Java 3D Alpha and I overwrote it when I install Java 3D beta 1.
