My OS is Windows 7 and Im using Firefox. I found four problems:
- The first page doesnt load correctly, even when the rest of the book does.
- The button for fullscreen becomes stuck once you press it (it works properly but appears to be in fullscreen mode all the time).
- Scrolling is a pain in the ass, way slower than the old reader.
- Pre-fetch doesnt appear to be working, in the old reader all the pages load properly and I never get to see a loading screen, while in the beta for every new page I get a blurry mess until it loads.
Anyway, Im glad you are implementing a Two-page mode, thanks!
EDIT: in chrome it works a lot better, no problem with loading pages, pre-fetch or slow scrolling, though the fullcreen button still gets stuck.
