Dear Maintainer,


   * What led up to the situation?
        I isnstalled js8call, and tried to transmit.
   * What exactly did you do (or not do) that was effective (or
     ineffective)?
        I pressed the tune button.
   * What was the outcome of this action?
        The waterfall was freezing, showing only one line of information. The
TX wasn't happening. Some application, including firefox wasn't able to play
videos. Can't exit JS8CALL. The GUI disappears, but the process remains there.
   * What outcome did you expect instead?
        Stable transmit of audio signals, no other app to break.
