Hey I'm trying to run an experiment with multiple parts, and in the second task I just need a plain black background. I have tried the style with every option to get a black background and none of it is working. We have a style file from another experiment that seems to do the trick but when we add the other styles we need to this file it stops working. I have attached the problem style file and the style we are working with is 98. If anyone has any suggestions we would greatly appreciate it!
