MouseTrap 4.0

Mouse Trap is a simple desktop security tool for Windows 95, 98, ME, NT, 2000, and XP. It traps your mouse in place and locks your desktop until you enter your password, while disabling system keys like Alt-Tab and Ctrl-Alt-Del to prevent tampering. It can hide itself in the system tray until you need to use it; it can also be configured to trap the mouse on system startup or at a certain time of day.
