I am having a problem with checkboxes. I have a previous PDF form that I open in livecycle. I have tried both ways to auto detect form fields and to open and manually do it. Problem is, either way when I add a checkbox it doesn't work. If I add just one checkbox, it works fine. But if I add multiple, users can not check a box. You click on it, and it dosen't do anything. Am I missing some hidden step?
