Cannot redelpoy or undeploy

The items undeploy & redeploy are greyed out in the
right click popup menu even after the jar file has been
deployed.

Using the ctrl + Alt + F8 key will redeploy correctly,
and the 'Deployment' screen in the 'Properties' window
for the file says that it is deployed, but the items
are still greyed out.
