Wow! This works great. Thanks Pablo. I was looking at the Fitaly website out of interest, but so pleased to find your article and see how well it works on my Palm IIIc up to 33% brightness. I had been hounded with this problem, and use contact cleaner regularly to improve digitizer performance/graffiti ability. I also always run at low brightness settings. Now, with Afterburner, it is much more consistent and my speed of graffiti entry (less correcting) has improved significantly.
