Don't have a NOT function to track when a concrete text disappear from pages. It is a page change that this program can't track.Copernic have the worst support service I have seen.If you request the 30 day money back guarantee that they announce in their page, they will ignore your requests.Copernic Software sell DEAD SOFTWARE. You pay for the programs, but when you have a question because the help provided is incomplete, nobody answer to your questions, or their answers is about wrong product (automated answers?). Shocking.
