Hi, apologies if this question is a) daft or b) has been asked before, but I am in the process of formatting my book for epublishing and have hit a potential snag. My book has quite a bit of dialogue, and in the majority of cases this starts on a new line so I have a hard return. Unfortunately this appears to be recognised as a new paragraph and as a result it has a first line indent and a space before and after. How do I get rid of this, either in the draft, before any formatting is done, or after I have done it? This is a (very) long term project so I am quite happy to go through the book again (and again) if necessary. Many thanks for any help you can give.
