I would like to have a response (a black "x") come up when the participant presses the incorrect key. I understand that previously the only way to do that is through jumping to a new frame and then coming back to it. However, this forces me to create a new screen. What I am wondering is if there is anyway to add the black "X" on the screen that i am indicating they responded incorrectly to? With the jumping as it is now, the screen refreshes, which takes a moment, and then shows the "X". Is there anyway to add
it right on the screen itself? Just like the incorrect.txt shows up, but without having to push the correct response to move on?
