Hm, just coming from testing, but even more odd:
After switching on the standard driver (of course switching off the extended), I first fetched the book again, converted it and - just to try - applied the Hyphenate-This!-Plugin. Then sent to device.
Result: Issues showed above vanished, but instead, there are many, many punctuation marks of any kind (.,.,;,!, even quotation marks) that don't rest immediately after the last word of a line, but stand alone in the new line. Very ugly!
Removed the book, either from device as from bibliotheque. Fetched and converted the book again, now without using the Hyphenate-This!-Plugin.
Result: The same!
My God! What is this? Until now, I considered the basic driver as 'asset of the last resort' (please don't mind!) in the case that the Extended driver wouldn't work properly. But this time, the Extended works more consistent. Nevertheless, my impression is that's me who did something wrong.
