Nice problem solving
Just wanted to confirm that DirectRT does in fact read stimulus references in a stim list as if each were literally transplanted within the cells of an input file. And, as by default, images require no prefix character, entering the stim dog will lead DirectRT to search for an image called "dog.bmp". If it can not find the image, it will display "dog.bmp" on the screen as a placeholder. If the word dog is to be presented as text then it would need to be entered as ~dog, or as a sound, !dog, etc.
And yes, I do believe that quotes are a problem for stimlist content as they can be mistaken as data / field delimiters when DirectRT is reading the file. We will try to resolve this in the next version.
