I was listening to the podcast and fiddling with my keyboard and all of a sudden you disappeared, or at least the audio did. I am on firefox.
My audio is fine on other functions. Media player etc. There appears to be a bar through the audio playback display.
I tried googling help and displaying the answers but nothing has helped.
Thanks,
Marilyn
Editing to say I have found it shift+cntl+v will take the block off.
