I do get this problem in both the CSV and SPSS files for byQue, and byVariable (see attached zip file Au2010 NC...).
I also have tried to systematically replicate the problem using the Recall.que file in between the two questionnaires that it follows and precedes in the full experiment. However, I have not been able to replicate the problem using 30 different variations of responses (see attached zip file Au2010 test).
I will now try it with the updated final release of v2008.
