#3 Permutation buffer error

[Anonymous]

When running main, the window containing the cells of
sudoku opens; i insert some numbers and click "solve"
button but it stops saying "Permutation buffer is full with
500 elements".
Solutions?
thanks

Yeah, when I put a value at cell (1,1) and press "solve", it
says: Permutation buffer is full with 500 elements

Try to set the "strategy" to Guess. Then the program can
solve the puzzle.
