Occasional freeze on old 3DS upon app exit

[KJeff01]

Sometimes the app will freeze when pressing the home menu button and then clicking the close button. My 3DS gets stuck on the informational popup menu that appears when an app closes (telling you that the app is closing). If this occurs I must force power-off the console by holding the power button for 15 seconds or so.

It can happen when exiting via the Start button too, but instead it will cause the screens to stay black and, again, force a power off.

It's not very common and probably happens around 10% of the time I play it and this is the only app I have seen exhibit this issue. I installed the .cia version via the Universal updater app if that matters.
