I followed the example found in Section 5.4/page 12 of the tutorial found at
http://www.grotto-networking.com/JUNG/JUNG2-Tutorial.pdf. However, when I right click
on the GUI to add/remove a vertex/edge, previous options that were available
to me as well as the current options available appear in the pop-up menu i.e.
the more I right click on the GUI, the more options that become available to
me. Is there a way to fix this such that only current options are available
to me? I am using Jung 2.0.1.
