We have recently created a customized html item with multiple questions with multiple radio-button responses. We would like participants to be able to press "continue" without having to answer any of the questions. When we've tested the page without answering any of the questions, we saw a blank white screen upon pressing "continue" and Media lab essentially froze (we could not close the questionnaire without turning on the task manager). When we answered one or more question, we were able to press "continue" without any problems. Any ideas on why we only have problems when we answer none of the questions?
