Hello,
I was trying to find a clear answer for when data is written to the .csv file. I've always been under the assumption this happens when the "OK" button is clicked at the end of the questionnaire, but it's become important for me to know this with certainty.

We're having issues with password-protected screensavers popping up, then other lab staff "kicking off" prior users by terminating their idle sessions. I have a theory that if this is happening after the screen has gone idle waiting for someone to click "OK" that the data isn't getting saved when the questionnaire-administering user is kicked off the machine.

One way or another, we're missing a participant's data!
