Sorry for the late response - not as much time available as I'd like.
I wish I could tell you why your screen appears unclear. I've never heard of that problem before. I think there've been a number of Clie users and they seemed to have no difficulty with CarbCheck as far as I can tell.
Is your Clie a color model? That might explain something as I wrote the program way back when all I had was a monochrome Palm III -- and the development platform didn't support color. I've never gotten to updating the program since I've since switched to the Pocket PC. If color is the culprit, I wonder if there's a way to temporarily force the Clie into monochrome....
Other than that, I'm afraid that I've got no answers. Sorry about the trouble, Jenn - wish I could be more help.
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.
