consider restoring "bottom row" of earmarks
Submitted by William Melgaard
Previous versions of Sudoku provided three popups per square: two text boxes and a menu for the value of the square. Either the top or bottom textbox could be used to list possibilities. Without this capability, Sudoku is virtually unplayable. At present, clicking anywhere on the box does not provide a textbox. The documentation says that it is possible to set tracking from the toolbar. There is no toolbar. It would be nice if the linex bordering a 3 X 3 set of boxes sere heavier than the lines around the individual squares.
