I have been trying to get Jitsi to replace Skype and have downloaded and installed the Jitsi client on my Ubuntu 15.10 64bit system. I have set up an account with jabber and can see the account in Jitsi.
However, when I click on the 'About' item in the 'Help' menu a window opens and nothing else appears. I cannot close the window, I can't 'Quit' and the only way I have found to shut it down is turn off the computer.
Is this a known bug and if so when will it be fixed?
