I tried Pivot and added the following to registry. Whoever wants to try it can save it to a *.reg file and double click the file to import it to registry.
"FriendlyName"="Touch Pen (Portrait)"
After import it, go to control panel -> Pen -> General -> Pen Options -> Model, now you can select "Touch Pen (Portrait)". There are a couple of problems:
1. After you select new model, you have to reboot.
2. After reboot, If there is network login window, you cannot use pen to input password because Pivot hasn't rotate your screen yet but Pen service did.
3. there is some offset at X after rotation, even I calibrate the screen cannot correct the problem.
so before try this, attach a mouse to CF-01, otherwise you will try to click the screen everywhere to close a window.
Overall I am impressed, I ran Palm OS Emulator on it, everything works like a real Palm, I guess I can use my CF-01 as Jumbo-Palm :)
BTW there is a crack for the trial version, just FYI, I am totally against using it :)
