This only works in Win9X not NT/2000. See KB Article Q161133.

What you are essentially doing is telling the OS to act like the screen saver is running. It is built into 9X to disregard the reboot/menu keys if this is the case, not NT/2000.

IAC, this function only works with the "reboot" keys. You can't define your own set of input to ignore.
