I downloaded the latest Black Ink (1.1.6 - 530) hoping to fix the bugs with multiple letter entry. Unfortunately, I think there are still issues. In the 2008-01-11 Sunday NY Times puzzle, for example: when I enter the correct two letters into the second square of 2-Down and check the word (or entire puzzle), the first letter is marked as red, even though I know I have the correct two letters. Also, when I reveal, only one letter is shown there (likewise for the other circled squares).
I like the interface of Black Ink *so* much better than the clunky Across Lite, but the bugs are definitely distracting. Any thoughts on another go at fixing the multi-letter entry for the next version?
