Palm OS Guide/Troubleshooting
Sometimes your digitizer(touchscreen) goes out of alignment. You can usually align it by going to the Prefs app. But what if you screen is so out of alignment you can't go to Prefs? Install Z-Digitizer. It will let you align your screen after every soft reset. So just hotsync Z-Digitizer to your palm, poke the hole at the back, and you're back in business!
