The registered version of Buddy lets you set a global password for your 100LX in Buddy's Other Settings screen. You must press (%) before you can access the password field and enter a password. This makes it a little more difficult for someone else to change your password.
Tab down to the Fn-F Password: box, enter your password and press (F4) (Quit). The password is activated when you press (Fn)(F) to turn off the Palmtop. The 100LX will ask for the password then you press (ON).
This feature disables (CTRL) -(ALT)-(DEL) reboots, but can be circumvented by a (CTRL)-(<Shift>)-(ON) hard reboot.
