In my medialab experiment (a series of questionnaires), I include a password screen to ostensibly end the study for participants. After updating medialab to 2010 on windows 7, I received an error (Runtime error 5) when my experiment reached the password screen.

Fortunately, after talking with Dr. Jarvis he was able to fix the problem, and the recently posted 2010.2.18 version of media lab (on the main download page) has fixed the problem with the password screen.

If anyone else is having the same problem, download the 2010.2.18 version (save it to the medialab folder on your computer) and you should be all set. My experiment now works just as it should!
