    Guys, In my case, it is not a hidden window, but a window that has been minimized that causes the audio interruption when I activate it again.   Ed, K0KC

      It may be working fine for you, Joe, but I have noticed this audio interruption too, but I always chalked it up to my aging Dell Inspiron laptop running Windows 7. Both WSJT-X audio devices are clearly listed as my external USB sound device and not any Default device you mention.
       
      I mentioned it only as a “yeah, it happens to me too” type post before seeing Joe’s, K1JT acknowledgement of the issue. I see no need to pursue this further unless it continues to happen after any fix for it is released.

      I've run multiple tests here (Windows 7/64, external USB sound card,
      WSJT-X v1.2 r3563) with *no* audio interruption when making a hidden
      window active or starting another application as long as the USB sound
      card was *neither* the "Default Device" or the "Default Communication
      Device."
