New feature: When solving a problem interactively it is now possible to mark "candidates" for cells. When printing, these candidates are printed also.
Corrected Bug: When calculating more than one solution for a problem, it happend in some cases that the displayed solution was marked as "invalid" even though it was a perfect solution for the given problem. This has been fixed.
Corrected Bug: When prining a problem it sometimes happend that not only the given problem but also some other (calculated) values in some cells were printed out. This has been fixed.
New feature: The program now shows only those hints, which are quite obviously and not dependent on solving other hints.
Corrected Bug: In some cases the program didn't handle modified problems correctly. This has been fixed.
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)
Corrected Bug: The option "Hide when minimized" didn't work as expected. This had been fixed.
New feature: The program now displays hints in different colors (red for obvious cells, orange for cells harder to detect).
