Hi All,
Up until about a month ago I successfully made surfaces from jvxl files that I copied from the console using the show command.  Since that time the surfaces generated from the jvxl files are not the same as the original computed surface.  The jvxl files made before that time still generate the correct surface.  The link below contains two examples.
