Sorry, I don't know how to do that. With all the mistakes I've made in a rush to set the device up for my wife to read her book, I have files in different folders, I'm not sure which is which now! There's been so much different software to set up, and processes I don't fully understand that I've had to go through, just to get a couple of ebooks on a new ereader, my head is spinning

. At this stage, the ebook shows up in Calibre, ADE and the Sony Reader, and she's reading it happily on the Sony. If I purchase any more Kobo epubs I guess it will be worthwhile to learn how to alter the CSS, but at this stage I haven't seen a CSS file.
I really appreciate you taking the time to help me, but I've come to the whole ebook process in total ignorance.
Can I somehow delete that attachment?
