mdclements, thanks a lot for the suggestion. Renaming the file did the magic. The content display correctly now.
I still have two issues though, hope you can help me out:
1) After renamed the file, the book cover changed to a generic book cover rather than the original book cover.
2) I could NOT change the font size: after pressed bigger (or smaller), it showed as "updating", after "updating" nothing changed. Any clue?
