I know this is old, but I have encountered this problem - despite very careful attention to the instructions, and to spelling, I cannot get the 'No' choice to jump to a different question. The client must click through all the intermediate questions.
If they select the 'Yes' choice, they are presented with the proper question. It would really be useful to have the user able to skip ahead about 30 questions, when the answer is 'No' - but really it is no different than just selecting N/A to the dependant question, and ignoring the dependance feature altogether....
FWIW, none of the intermediate questions are marked "required"
