I have an issue with a program where, midway through, a screen pops up that says that an particular image file cannot be loaded. I have to force quit in order to get out of the program (pressing escape does not work).
However, I have this identical program on three other (identical) machines, and I do not have this problem on any one of them. In addition, I have four versions of the same experiment (different stimuli in each version). So far, only a single version is having this problem, and it does not appear to happen every time.
Any thoughts on what might be causing this problem with loading the images?
