I don't know what's up for sure, but the "a-christmas-carol2_post-Sigil.epub" I attached to post #41
ignoring the CSS (paragraph styling, drop caps, etc...) using AZARDI 8.2. I see no difference. I even went as far as to completely remove AZARDI (every bit of it ) and download and install 8.2 fresh. No luck. It just doesn't properly display ANY ePub2 I've built (with regard to CSS).
