I don't have any DRM'd books. So not sure what happened. For the moment, I have it back to the 01/20/09 update from Hanlin. I have converted all my LIT books to MOBI just because I like the way they appear on the screen better. But the bookmark doesn't work anymore (pushing 1-5) like it did on the LIT files. When I push 6, a new Bookmark screen comes up, but it's empty.
Thanks for the info about OI. I'll keep that in mind.
