Forgetting which apps to lock and crashing on configuration.

[Inu-Yasha]

I find this app to be the only fast enough AppLock probably because it doesn't have ads!

But I have two major issues. 1st one being that it crashes almost every time I go to configuration page.

2nd, I've found it necessary to visit the app every week and check if it remembers all the apps I've chosen to keep locked, because it usually doesn't. Sometimes I just notice that an app that should be locked can be launched without having to unlock it, and that's especially bad when that app is Android "Settings" app - and it happens really often. I have no idea what could cause it to forget some, but not all of my choices.
