I have noticed that the issues are coming up each time you embed the Yes/No question into the text before the question. I do not like the structure that you have created. I used Point 42 on page 13 as the test. I restructured your flow there by making the text for the question a text box, then moved the radiobuttonlist after that and then the field to capture the information. I then separated the subform into two smaller subforms and made those positioned and then made the root that you had flowed. The hierarchy of the objects is important and will affect the layout. Have a look at what I have done in this modified sample and see if it fits your needs ....if so then restructure your form in this manner.
