I had to update this thing due to a change at work (my 3rd employer since authoring the script). On their rolling out of the new Win7 boxen my script quit working. And get this! My company's IT department itself asked me if I might fix it. How cool is that?
So I borrowed a loaner Win7 laptop, installed Strawberry Perl and changed the timing to update every minute (verus the fomer two minutes) and changed the default character set to a pair of SCROLLLOCK's (as per suggestion above). Those two in combination seem to have worked at least on this loaner laptop.
While I was editing, I couldn't resist adding in a few new options. Foremost is to offer the choice of using Tye's mouse jiggle feature. This you may choose to employ either together-with or separately-from issuing key strokes. You also have a choice of key strokes.
Lastly, while running it will check to see if the mouse has been already moved by the user. If it has then the script goes back to sleep for a further minute.

# Name: gus_screensaver_defeat.pl
# Copyright: Gan Uesli Starling, 2004-2012
# Purpose: Keeps Windows screensaver from tripping for as long as need
+ be.
# Changes:
# Char string is now a pair of consecutive scroll locks.
# Loop time shortened to one minute.
# Added modification of Tye's jiggle-mouse function from PerlMon
+ks.org
# Skips current trip-loop if user has already moved mouse.
