Up to version 2.5.7, it was an excellent program. With this version, I have encountered a couple of bugs which have forced me to start looking at a possible replacement. In previous versions, I was able to create my puzzles using MS Excel X and then copy and paste them into the Susser grid with no problems whatsoever. In this version, it refuses to let me paste the puzzles into the grid and gives me the numbers in the comments area without pasting them. I have also had the program give me an error message after manually entering the data into the grid and saving it as a new puzzle, telling me to use a command which doesn't exist.
