Small and capital letters in the correct_response column
I'm teaching an online course about (among others) opensesame.
One student, that uses Mac and the current version of opensesame, used the letters 'k' and 'D' to define correct responses.
In the keyboard response she entered 'D' and 'K' as the allowable responses.
Testing the experiment (on a windows computer), I had the caps lock off.
I expected correct to be 0 since d is not the same as D.
Is this a bug or a feature that allow for flexibility?
