Unpredictable keyboard response

We are having troubles with the Key-board sting imput accepting what is typed when running the experiment. It will accept letters in an unpredictable fashion. Many times one has to push a letter multiple times before it will accept it. We have uploaded the file.

Thanks so much for your help

This is a common problem with the string input feature. I have taken a look at your experiment and believe to have found the issue. Please see the thread below.

Make sure under participant input for both your input devices (single key and string input) that “Only if an event designates a single key as correct” is checked.
