My nook updated without any problems. My only 'complaint' is that the page numbers and title color is now permanently black when reading. The page number / title of book used to match the color of the text. I use the mocha theme in the evenings and the page numbers are not white anymore, same when using night (black) theme.
I have the same problem with my Nook Color. As I use mine mostly in low-light conditions it would be nice to have the papge-count readable again.
Any Nook devs/engineers reading this know how to fix the problem?
