The issue with the unit going to sleep 3 seconds after the screen times out also happens when I am streaming NPR audio. Where do I allow apps to keep unit awake? I still don't think that the system should go into sleep so soon after the screen time out. The time for system sleep should be independently user selectable & I can't find out where to set this. I have tried playing MP3s with the PDplayer & it keeps the system awake. Cheers,kev
