I created my own Sudoku Solver, The input and output system are improved, the english and dutch version have identical interfaces now. And work the same.
You can find it here:

Download links are one the bottom of the page, the archive contains older versions.
Note: I noticed that the forcing chain EXPLANATION sometimes is a little too short, it's conclusion are correct, but explaining the steps is sometimes wrong (short of some steps).
Hope you like it
I updated my software, it now support sword and jellyfish, all kinds op pairs,triplets and quads ! And a brute Force multi-solution finding algorithm has been added !
