Having used this product on large (more than 500 pages) and complex documents, my conclusion is that this could be a very good product. Unfortunately, the software has some logic flaws that cause it to fail repeatedly on specfic text formatting. For example, consider the following listing:a. Data Elementb. Data Element Tagc. Element Numberd. Group NumberThe application always fails on this and similar listings by randomly deleting the new paragraph marker and setting the right margin incorrectly. Too bad that Scansoft support, which could alert developers to this type of problem, is the worst I have ever encountered. Perhaps someone from Scansoft will read this review and fix this problem and other problems encountered by customers.
