TaiwanSwedey - are you sure your new keyfile was installed? Did you get any message from the software telling you it had been activated?
There might be an issue with your old keyfile getting in the way, try this: go to
http://www.nosleep.net/ and download and install FileZ (if you haven't already), run it, tap on the button to edit your Preferences, scroll down and delete any entries with "PLEN" as the creator code. Then, install another copy of your keyfile and try unlocking again.
caesartg - thanks! That reader system is going to be really nice once it's integrated with the 5-way navigator pad, each direction will be mapped to one of those four highlight adjustment buttons and the center button will toggle between that and just moving the highlight cursor between lines / characters so it should be possible to navigate a document without ever using a stylus at all.
Jamie - try the just-updated application posted in the Bug Reporting Thread; we'd accidentally put in a system call that most pre-2006 Palms didn't support, ironically enough in the thoroughly-trivial function responsible for drawing the little letters in the dictionary switch icon, but we've now checked for / taken it out on those models so the software should start smoothly.
