this is my first post so please do not kill me for dumb questions ;)
Atm I'm trying to create a "SecureLock" Application using a RFID Card Reader. Everything is working fine except the fact that it's not possible to prevent the Task Manager from showing up pressing ctrl-alt-del.
I "solved" that problem hiding the App-Lockscreen from the tast manager BUT my app loses focus when starting the task manager.
For security reasons it's not possible to disable the task manager from the ctrl-alt-del menu.
Has anyone an idea how to solve the focus problem?
