By George, now we're gettin' somewhere! calibre 0.4.92 built an epub through the gui, added a cover image, working toc, working hyperlinks, fairly decent rendition of the styles (but some of that may be DE that I'm seeing as weird - the <Title> style isn't quite what I was expecting). Fabulous Work, Mr. Goyle.
Attached is the latest-generation epub example, and it works in Digital Editions! Still doesn't load into Cool Reader, and now my fbreader is hopelessly hosed (the app won't even launch). So, we can conveniently say THOSE other apps have issues until proven otherwise.
Can I re-trouble-again someone to load the attached epub into a Sony? (should be better now).
Oh, and has anyone written a css to handle the placements of the page numbers in DE?
