Pooja, thanks very much for your reply!
3. The cover issue is fine. I did prefer having control of this but I shall submit to the wisdom of EPUB3.
5. I tried again and encountered the exact problem. The CSS is: font-family:”Georgia (OTF) Regular”, sans-serif
I’ve defined Georgia with the paragraph style, no overrides. I suspect this is not a widespread problem then, possibly something to do with my font management program’s relationship to IDCC (Suitcase Fusion 4). I actually delete Georgia from my CSS anyway (I still design without embedded fonts, as I learnt to create ebooks when embedding fonts was riddled with problems – I’m happy to let the readers define the font until I’m confident any design embellishments will not cause problems on any reading platforms [has this day come yet?], but I find this glitch strange/new, so thought worth mentioning)
6. Thanks for the tip, I’d overlooked that option. I only seem to be able to add pixel for the margin, not ems, but I’m glad I can experiment with that in ID. Does anyone have a recommended pixel with for standard margins?
8. I find this a really odd problem. Can anyone explain exactly what this means and why it has changed (I cannot see any benefit, but would like to be enlightened if there is one). Also, are there any foreseeable problems not having the ISBN in these fields (which seems the easiest fix to output a valid epub file)?
Thanks for continuing the conversation. I’m only on my second book via IDCC (after years in CS5.5), so its early days, early days.
