I've inserted via cut and paste and via manual entry the following puzzle into SudoCue:

..84.2....2....1..4....562.1..34.7.9...2.9...3.9.17..6.419....2..5....8....5.14..

SudoCue gives the "Too Difficult Sudoku" Error and once I hit OK, it will declare the puzzle to be invalid. All techniques are turned on. What seems to be the relevant solver order choices are:

Skyscraper
2-String Kite
X-wing

If I switch the solver order to

X-wing
Skyscraper
2-String Kite

then SudoCue gives no such error message and declares the puzzle to be valid and solves it with no problem.

Any thoughts?
