unlocked.pdf - this file was enabled for Reader entensions. Notice you can fill in form fields and save.
locked_after_FillField.pdf - this file used ASPOSE Form.FillField to fill in a form field. Notice when you open it, it says Extended features no longer available and you cannot fill in form fields.
If you open unlocked.pdf and manually type in form fields, and then save the PDF to a new file name, notice that you CAN still edit form fields on the new file. Somehow Adobe Reader is "saving" the Reader Extensions characteristic even after modifying form fields similar to the ASPOSE Form.FillField.

I am having this same issue using the trial version of Aspose PDF 7.6.0. Is it only a problem because I am using the trial version?
We are evaluating the trial version to see if it will meet our needs and so far it seems like it will if this issue is no longer a problem and works in the current version.
Specificaly what I would like to know is
Is this just an issue in the current trial version?
Will the paid for version of Aspose PDF version 7.6.0 solve this problem?
