How do I stop LL2.2 from auto-logging out when listening to a podcast?

Have a look at your power settings, Menu > Settings > Power Manager.

That's the screen lock. Menu, Settings, Light Locker.

Hmm I didn't know we had a Light Locker Settings but when i click on it, it immediately closes right away before i can get a look at it.

When listening to an already downloaded podcast, using the Clementine media player that comes with the LL2.2 bundle, LL will somewhat annoyingly log-out automatically with regularity, i.e. ~ every 5 min, and the LL login-screen will then appear.  When this happens, the podcast continues playing but it can't be heard – this means that when I re-login, I find that I have missed some of the podcast and have to rewind to catch up on what has been missed.  What setting do I need to adjust to prevent LL2.2 from logging out automatically when listening to audio.

Many thanks for your help
