Thanks for getting back to me - especially with Thanksgiving right around the corner.
So, I tried what you suggested. I just moved the skip after only 1 set of videos so that I wouldn't have to sit through 30+ minutes of videos.
Anyway, with only 10 blocks, I did get the thank you screen but then the screen went blank and no popup at the end occurred. I had to do a control-alt-delete to get out of the program. This is reminiscent of what was happening before when I had the skip after 25 blocks whereas for the study now it is after 15. At least it did not close out the program before the thank you screen.
So, then I tried it with 8 blocks, I got the thank you screen - it stalled for a little bit but then the popup finally occurred.
I'm attaching both questionnaire files so that you can take a look. The test1 file has 10 blocks - the test2 has 8.
Now what do you suggest?
