I just noticed a problem with my Nokia 1020 that's running on Windows 8. Anyways, after playing around with it, I found out if I wanted to block an app from running in the background, I should go into the settings and check the ones I don't want running. But no apps are showing up so I can't click on any. I'm not sure if it's a Windows problem or a Nokia problem. Can anyone share some advice on what to do?
