While it's always possible that our business users could require editable form fields in the future, right now we don't need editable form fields in the PDFs. We were only using the PreserveFormFields option in order to make the check boxes appear correctly.
The business scenario is that they give IT a Word document with instructions to convert the document to a TIF (in which case editable form fields don't matter) or to convert the document to a PDF. In the latter case, I don't believe form fields matter, either, because the PDF is emailed to a customer for them to print out. No one has asked for PDFs to be editable, but you raise a good point and I will need to follow up with my business partner to find out.
Either way, if the latest version of Aspose fixes the checkbox problem, that should also fix my problem.
FWIW: I realize I've posted a number of issues to the forum lately, and I appreicate Adam, Alexey and your help in sorting through the problems.
Thanks for your time.
