    Hi, I'm using WH_MOUSE and WH_KEYBOARD hooks to sense user movement just like a screensaver. The screensaver prevents the hook messages from reaching the program. Therefore I disable the screensaver when I enable hooking. Now I've realized that if the user locks the computer manually - by pressing CTRL+ALT+DEL and afterwards the "Lock Computer" button, then the hook messages never reach the program. Is there a way to let the hook messages pass beyond the logon screen and reach my running program? Thanks in advance...
