Visualization plugin does not appear to work with Cytoscape 3.8.0

[alexweisberg]

I am trying the Cytoscape visualization plugin to rearrange the network of the example dataset (5 E coli genomes). I followed the instructions to install the plugin and it appears in the App Manager window as installed, version 0.1. After loading the example edges and node tables and adding the search and coordinates columns, nothing happens when I click on Select -> PGN Arrange nodes. I tried selecting all nodes and it doesn't do anything then either. Am I missing a crucial step, or is the plugin no longer compatible with the current version of Cytoscape? Thanks!
