	Purpose
"Lock" the computer until the user types a password.

	Method
Use a timer to grab control frequently.

Note that this program disables Ctrl-Alt-Del for Windows 95. This does not
work for Windows NT (I don't know about Windows 98). A timer regrabs the
focus many times per second so it is hard for someone to do anything useful.

However, they can use Alt-Tab to see what else is running and they may be
able to use the Task Manager to quickly kill processes, though they will not
have time to pick a specific target.

All in all, not a perfect solution for Windows NT but a very interesting use
of timers.
