Gosh, don't even bother with v.35g. It totally breaks epub's zoom feature.
I wonder why ectaco releases firmware that has bugs the size of a bus? I could spot the awful bug within 2 minutes of use. Don't they even bother to test them for 10 minutes before releasing them? Even if it is a beta release, it's such an obvious bug that it's an insult to users and a waste of our time.
Edit: I tried a few more epub. Looks like this release tries to fix the zoom level (ie font size) bug. The text doesn't reflow for some epubs, but it seems to work for others.
