It is hard to imagine how this is a VisAD bug.
It could be that the Java3D GraphicsConfiguration
must be different on different heads (although
that would seem to outlaw dragging Canvas3D's
between different heads). You might experiment
with the DisplayImplJ3D constructors that take
non-default GraphicsConfigurations.

I don't have any dual head displays, so someone
with one (you?) will have to work on this. Let us
know what you find.

I also suggest joining and sending this question
to java3d-interest@xxxxxxxxxxxx.

Good luck, Bill
