Thanks to gnuite, John Costigan and the developers.
I got the latest version running on OS2008 on my N800 without any problems. It works great. Connected to my GPSlim236 effortlessly. Downloaded lots of maps of my favorite places. Figured out how to set route points and way points and how to download directions over the Internet. This package puts Wayfinder to shame. It gives me what I need to keep from getting lost, and it's a blast.
Cheers.
