Hi - I've attached a zip files, please let me know if you have any trouble opening it or anything.
As you requested, I minimized the input file to ten trials and included the style file, and only the stimuli necessary to run it are in the stim folder. I ran it this way and it still shows the problem.
When you run the file, you can click the left mouse button to get past the instruction screen.
Thanks for taking a look, I hope your expert eye will notice something that I didn't!
