New feature: The "Track"-option now shows the whole solving process including those cells that are not solved using backtracking.
Please note: Due to internal variations this version isn't compatible with prior versions of Sudoku. If you have already installed an older version of Sudoku you must uninstall the older one prior to installing the current one (using the regular "Add or Remove Program" control panel of Windows XP). The automatic update will not update older versions of Sudoku to the current one! Version 220.127.116.11 (2006-11-12)
