For years, I've been using the form tools within Acrobat Pro to create PDF forms for my users who only have Adobe Reader. All in all this has worked well but recently, I've started getting complaints from them that they can only fill out a form once and can't change the contents of the text fields after the PDF has been saved and closed. To be clear...
This may seem like a dumb question, but is this...really...expected behavior? If so, here's the kicker. If I open the saved PDF form in a web browser, the text within the fields CAN be changed and saved again.
If this is NOT expected behavior, how do I make a PDF form so that it can filled out and subsequently changed later as many times as needed (purchasing additional licenses of Acrobat Pro for my users is not an option)?
Don't add the extended features.
Hi Bernd, that did the trick!
Thank you so much!
Hope you are doing well and sorry for the trouble.
