I use interactive pdfs to collect survey and quiz information from students. The pdfs have a Print button and Submit button that work fine when the pdf opens in the reader. Neither button works when the pdf opens in a browser which seems to be the default now. I can't tell users to change reader settings since I don't know in advance who they are. Because "open in browser" is now the default I have a large number of interactive pdfs that don't work now. Is there anyway I can force the pdf to open in the reader and not open in the browser or fix the print and submit buttons so the work when the pdf opens in the browser? Desperate for a solution.
