Since I've upgraded to iOS 6.1.4 I've noticed something a little odd. If I open the task switcher (hopefully that's the correct term) and close all of the recently opened apps, then do a full reboot, up on rebooting all of the apps ARE BACK that I just closed. Anyone else notice this? I don't have any functional issues due to this, I just noticed it and it sorta ticks me off that the apps all show up again after i just took the time to close them all.
