Size limitations

I have a questionnaire with over 300 questions. During the running of the questionnaire, Media Lab goes to a blank screen after 155 questions. I have tried deleting the questions around the problem area, but it still stops after 155 questions. I could run the questionnaire in 3 parts if needed to get around this, but I would rather not. Any clues as to what's happening and how to fix this problem?

Are you running on Vista?

What version of MediaLab are you using? The newest copy available (1.33) may fix this problem.
