Strange, strange! Now that I'm working on another book, on a sudden, the Check Dialogue works again! The appearance is different than before: as I remember, there had been a box in the popup where one could deny to do any changes. Now, there is only the "Back to the Procedure" button, and to continue, I have to interfere in the text, at least by removing the highlight. Only then I can activate the CD to continue.
However, I don't know what you did, but I'm really glad!
