Actually my problem is that it merges lines it's not supposed to merge.
I find it strange for OCR software that there's no simple way to tell it what to look for when trying to detect new paragraphs.
Most of the texts I scan use indentation but FineReader seems to be oblivious of the idea that those may be new paragraphs and happily merges them together more often than I would like.
The 'keep page breaks' is definitely some help but without being able to see this in the scanned text window it's only half a solution because I still can't use FineReader's editing features efficiently.
Most of the other problems it has - the inability to edit across pages, for example I can deal with by using text cleanup tools afterward. It's really the lack of control over paragraph detection that has been a constant irritation for me because as it is it creates more work than it solves.
