#255 Algorithm error in v2.2.0

[nah]

I'm a user of version 2.2 and clicking on report error from the menu takes me to this page, even this page seems to be for version 2.3.

I start with givens:
0,0,0, 0,0,2, 9,0,4,
7,4,0, 3,6,0, 0,0,0,
0,0,0, 0,4,0, 7,0,0,
0,0,3, 0,0,0, 0,1,0,
6,7,0, 0,5,0, 0,2,9,
0,8,0, 0,0,0, 5,0,0,
0,0,5, 0,8,0, 0,0,0,
0,0,0, 0,7,4, 0,5,2,
2,0,7, 1,0,0, 0,0,0

Under Preferences/Progress I choose Full House, Naked Single, Hidden Single, Locked Candidates Type1 and Locked Candidates Typ2. From the Hints window I press "solve up to". In box 7 (row major, starting from 1) I get 4,x,5,0,0,0,2,y,7, where x and y are blanks. So far this is correct.

But I also get 3 as a possible candidate for cells x any y. This is incorrect. Since boxes 8 and 9 do not have 3 as a possible vale for the middle row, rows 1 and 3 of box 7 cannot have value 3.
