New Feature: The calculation of valid values for a cell now also identifies "Locked Candidates".
Corrected Bug: Some internal cleanup/improvement efforts.
Corrected Bug: The version 22.214.171.124 might be faster than all of the others, but unfortunately under some circumstances it crashes when creating new problems. This has been fixed (without slowing down the application excessively).
New feature: Some really convincing performance improvements for generating new problems.
New feature: Besides the "Watch Hand Method" it is now possible to show and print both possible values and candidates as digits.
