We're running a pro bono CiW survey from a kiosk at a church meeting hall. The setup is 2 laptops that happen to be running Linux (the Ubuntu version), connected to a wi-fi access point in the same hall.
Roughly 1/3 of the time the survey fails -- the user gets the opening page, presses Next, and nothing happens.
In other online surveys we typically get 1%-2% of users who are running Linux computers, and they work just fine.
Any ideas? Does Linux need any special configurations to work well with CiW?
