Help Long press on home button not bringing up last screens

[Gfplux]

I have had my note 2 for 10 months and love the long press on the home button that brought up recently opened screens.
Now suddenly the long press has no result. Have I by accident changed a setting. Any help please.
Thanks

Probably not. There are numerous applications that do not appear in the recent list.

Just rebooted and it works again.
However after 10 months that worries me.

I've owned my Note 2 for around the same amount of time and this has happened to me around 3 times with no other noticeable issues. I think it's just a minor software glitch and nothing to be worried about.
