I haven't seen that behavior with paragraph spacing in ADE. ADE has some issues with other things tough and the ideal situation is that you test your ePub on the device that is intended for. That said, how did you create the space between paragraphs?
Just noticed that you mention using paragraph return for paragraph spacing. The consensus here is to use the Space Before/Space After feature for paragraph spacing. You can integrate this in your paragraph style so you don't have to do it manually one by one.
I have been using paragraph returns for the spacing but I will try adding the Space before/Space After feature to see if that works better.
I'm taking my text from other word processing documents and shortening/breaking the paragraphs into smaller units for easier reading in ePub. It's easy and natural for me to hit a paragraph return where I want to break and form a new paragraph, and then insert a forced line break -- but I can try your suggestions.
I was just wondering why the system worked for me when reading on the iPod but Adobe Digital Reader did not seem to recognize the forced line break at all and only recognized the paragraph return if it was inserted AFTER the forced line break and not BEFORE it. Inserting the paragraph return AFTER the forced line break makes everything work on both units.
Well, that's one of the reasons to use the Space After feature. Try it and you'll see that ePub keeps the space you set for your paragraphs. By the way, I know where you're coming from. It took me a while to get used to paragraph styles when I started using ID. In the long run it'll make your life easier. It just take a little more work to set the document up, but when you need to make changes or adjustments is much easier with paragraph styles.
