Horrible-Doesnt turn off notes when a space is solved

I make notes of possible numbers in each unloved square as identify them. When I solve a square, that number should be removed from all horizontal and vertical squares. But sadly, this game does not, forcing me to take time to go back and clean up all relatedsquares each time I solve one. Horrible waste of my time!
