I have a complete grid.
I have character's name (7,8).
I have the other name (5, 3, 5).
In the grid letters 3 and 4 of the other name have to be replaced. But then crossing entries become non-words.
The small grid entry to be highlighted is not so small. It is 6 letters.
Hankir, have you done the bit where you swap two entries? I did that, it left real words, and the 'other name' (5,3,4) worked. I lkiked the sneakiness of the 'small grid entry'!
