I haven't tried this app yet but I tried to solve this problem. I don't know what this will do to the rest of the apps on my Clie, but I went to "Prefs". Selected "HiRes". Checked the "Enable" check box, and Waala. Now the screen is readable.
Thanks for that tip. That's great news! I'll add that to the documentation as soon as I get the chance. Thanks again for sharing that. And, I hope the rest of the apps remain unaffected. Let us know if you can.
