I want a program to detect if the user is using the computer (i.e. mouse and keyboard movements), and if the user doesn't type or move the mouse for a specific amount of time, it executes a command.

However, as soon as the user presses CTRL-ALT-DEL the Windows Security Screen comes up and it is too fast for VB to detect that the keys have been pressed.I did a little reaserch on how to work around this issue and found that a GINA stub can be written which can delay the Windows Security Screen by some time say 2 secs which would be enough for VB to detect that the keys have been pressed.Also disabling Ctrl-Alt-Del through VB does not work because it is too fast for VB and I would like not to disable CTRL-ALT-DEL
