Query: Riddled with Errors

The available features are very handy, and the program allows you to zoom in and out which is helpful for those of us not blessed with 20/20 vision. Navigation is simple and intuitive. Overall, the program is pretty much what you'd expect in a crossword puzzle.The most disturbing problem is the extraordinary number of typos present! Many times, two letters are transposed in the puzzle and you will be told that your answers are incorrect; to have the program count your efforts as a "success," you must know the _REAL_ answer and then play around with the letters to make it match the program's _incorrect_ answer. I was quite disappointed by this particular flaw. While I have experienced the same problem with other crossword software titles, I had hoped that a product associated with the New York Times would have placed a higher priority on accuracy. It's disheartening to see such a fine paper lend their name to a clearly inferior product.
