Right click not working on outgoing change sets

Hi,

I downloaded and installed RTC client 3.0.1.3 to my existing eclipse, Juno, via p2 install repository.
Everything works fine except that nothing happens when I right click on an outgoing change set to bring up the context menu so I can deliver it.

Does anyone know what the issue is here or a workaround?
Right-click works on other RTC views but doesn't work on the Pending Changes view once I right-click on an outgoing change set.

Thanks,
Andy
