MAZELOCK.EXE OS/2 2.X Mouse and keyboard lock
by Jean Cyr, Feb. 1993

Here's the scenario: You've got a half dozen windows crunching
away on your OS/2 PM workstation and you need to go to the can.
You don't want to leave your workstation because all the pretty
windows are bound to attract some curious passer by, who can't
resist a mouse and will generally screw up your session. But you
really must go to the toilet.

MAZELOCK solves this little dilemma by repeatedly drawing and
solving mazes and blocking all keyboard and mouse inputs till
a password is keyed in. To specify a new password or change and
old one, fire up MAZELOCK giving it a single parameter: the new
password.

Example: >MAZELOCK mysecret

MAZELOCK remembers this password, so you don't need to specify one
every time. Just type:

>MAZELOCK

Unless you need to change the old password. You can, of course,
initiate MAZELOCK from a workplace icon once you have provided
the password.
