User issue
A user had https://groups.google.com/forum/#!msg/cytoscape-helpdesk/tZFTbxbTBpc/cgj66WAsCQAJ;context-place=forum/cytoscape-helpdesk with it a long time ago. Not sure if still worth looking into it, maybe for people who google for it; odds are it's no longer relevant for the new plugin version if that ever gets released.
