Yes, there do seem to be different issues going on here! TFK--If I recall correctly, there is only one correct column created for any given trial. Its primary purpose is as a convenience for single response trials so that the user does not need to compute a "correct" variable during analysis. In cases though where multiple responses are collected, I believe the "correct" column is not as useful. It should correspond to the final response, I believe. If so, you should be able to see if there is actually 100% correspondence between TRUE/FALSE and whether the particpant pressed the correct key for their second response. If not, please feel free to attach your input and log data files and I'll take a look!

And Tamar--I think Tim and PsychBoiler have you covered?
