I am using MediaLab v2008.1.33, and I recently attempted installing this MediaLab version on a laptop running Windows 7 Home Premium (64 bit). After transferring the existing questionnaire files from the desktop version of the study (running Windows XP Home) to the laptop. After running several test trials on the laptop, I noticed MediaLab began freezing up at the same place each time. Basically, after answering questionnaire item #156, the program froze before transitioning to the next question.

From what I can gather, it seems MediaLab is having a problem loading more than 156 questionnaire items on the Windows 7 laptop as even after deleting all items past #156 the freezing still occurred after transitioning to a second questionnaire. I never ran into such a problem with the Windows XP desktop version of the study, and at this point I am at a loss as to what might be causing the freezing on Windows 7. Any suggestions?
