Using jSudoku 1.3.

My understanding of Sudoku is that a puzzle should have exactly one solution.  The first time I ran this program, I got stuck at a point where I absolutely could not continue logically.

Eventually I just started filling in numbers and I found at least two solutions.  The puzzle I was given was this:
1_____6_8
_2___6__7
_____3___
__1__9_8_
_438__97_
6____1___
5___9____
_326__71_
_9__1___2

One solution:
175942638
324586197
968173425
751429386
243865971
689731254
516297843
832654719
497318562

Another Solution:
175942638
324586197
968173254
751429386
243865971
689731425
516297843
832654719
497318562

This was with the default Difficulty slider position which seems to be just on the Low side of the halfway point.
