Why are some pencil marks disabled on the number selector?
A. By default, the number selector only allows you to select from the pencil marks, so if the pencil marks are incomplete or incorrect, some choices will be disabled on the selector. In other words, it assumes the pencil marks are both complete and correct, and then only allows you to select one of them.
You can change this behaviour from the options dialog - if the "Allow Invalid Moves" option is selected, you can choose any number from the selector, not just those that correspond to the pencil marks.

SadMan's software Sudoku game makes Sudoku more enjoyable and I recommend it to all my friends. The ability to print a puzzle enlarged for easy use, with or without candidates, is one of many ways SadMan enhances the experience of working a Sudoku puzzle. The software provides a number of options including help understanding the techniques required to solve a puzzle, asking for specific help when you get stumped, or for a harder experience allowing wrong number choices which could dig a big hole the user may never recover from. Thanks SadMan for helping us play and learn Sudoku.
