I'm validating a book now that has a random space in the middle of words, perhaps four or five times a page. The spell checker will catch most of these, but if the space appears in such a place that the characters before and after the space both form words, I'll never know. I suspect there's no way around this but reading the book through, which I may not have time to do. Any idea what causes the OCR to do something like that? Just curious, Lora
