Input files not working with certain style files? (case 17788)

[LRoberts]

Hi there,

I am running a modified Stroop task where participants receive one of two background colors. To accomplish this, I simply created two style files (one with a black background and the other with a white background) and put these files in different folders with the accompanying input file. The input files are identical in every respect but their names. I programmed the task to require a correct response before continuing.

When I run the file with the black-background style file, all works as it should. When I try to run the file with the white-background style file, however, I do not have to enter a correct response to continue; I can press any key listed in the input file. The input files are literally identical and the style files are identical with the exception of a few colors. (I am also having this issue with a practice trial but can fix that on my own once I know what's wrong.) Any ideas on how to fix this? All files are attached.

Thanks!
