I encountered two of the problems reported with the 1.0.04.12210 firmware:
- "Next page" skipping many pages. "Prev page" skipping back those many pages.
- A page being duplicated after pressing "Next page". On a subsequent "Next page", the correct page appears, but a few words are skipped. The duplicate page was at the start of an epub html file (forgot what the Standard calls it) - so that may hint at the cause of the issue. I "fixed" it by going to the TOC and re-opening that chapter file.
