Since the update of Adobe Acrobat Pro / Reader on Aug. 8, the software crashes upon applying a digital signature on a specific form of mine. After JavaScript is done executing, the prompt for digital signature does not appear, and the software crashes. If under a specific case, I manage to reach the prompt for digital signature, and I would cancel, the software crashes. The signature can be applied only when the user follows specific steps, but it has to be done every time the signature must be applied. After uninstalling the latest version and reinstalling the previous version of Adobe Acrobat (July 11), the software works correctly and the signature prompts does not crash the software.
