Preview does not save option choices in PDF form
I have created a PDF form (using Libreoffice) that works perfectly with PDF Reader Pro Lite, but not with Apple's standard Preview program. I've also heard from Windows users that the form works well in their environment.
The problem occurs with radio buttons - all other editable fields work fine. When the PDF form is opened and edited with Preview, all looks fine. But when the file is saved, the options chosen via the radio buttons are lost. You can print the form before saving it and the choices are there. You can also print the form as another PDF file and the choices are there too (but that new PDF file is not editable).
Is this a bug or a feature of Preview?
