1) Go into the css and insert
Code:
body {
widows: 1;
orphans: 1;
}
2) Make sure that the top and bottom margins for normal paragraphs are set to 0, and that scene breaks (a pause in the text to indicate a break in the narrative) are indicated by setting the margin-top value to the line-height (which defaults to 1.2em) on the paragraph that follows a break. The yawning gulfs you have between paragraphs in the pictures are just a waste of space and their margins aren't synced with the baseline grid, meaning the text wanders around.
It's
not an ADE issue. ADE may have a few problems, but I don't know why people blame it for epubs that have been poorly typeset.
