Well, that's interesting.  I've found that once a solution is found by Shredder,
that I cannot reset it to the original state.  Thereafter, it stores the
position somewhere, and remembers the solution.  Perhaps that's what's happening
with yours?  Or do you know a way to reset Shredder so it doesn't remember the
solution?
