I think this is a bug. I could reproduce the problem on my Windows 7.
If I set the Cytoscape property "maximizeViewOnCreate" to true, not
always work.
The work-around is to get the JInternalFrame and maximize it,
javax.swing.JInternalFrame f =
Cytoscape.getDesktop().getNetworkViewManager().getInternalFrame(view);
try {
f.setMaximum(true);
}
catch (Exception ex)
{}
