We probably aren't going to force users to navigate into a temporary folder every time they want to sign a document, so that is not a route we want to go down.
We posted this mainly just to see if other people are affected by this. For example, if you edit a document from DocuWare and digitally sign it in your PDF tool of choice, does the "Save As" pop up? In PDF-XChange it appears to happen every time and I do not see any settings to make it stop (I have posted on the PDF-XChange forums to check about all this).
Has no one ever run into this before? I imagine actual digital signing forces a save in many PDF tools so that it knows to lock fields down and disallow further editing. Otherwise someone could add a signature, make additional changes, and THEN save (doesn't really seem like a problem to me, but order of operations might affect such an "official" operation, especially if the signature contains a timestamp).
I cannot test Adobe Acrobat because I do not know how to officially digitally sign something, just the cursive pseudo signature Adobe generates for you. And going back to Adobe isn't an option anyway since we really like PDF-XChange and can't very well change our preferred PDF editor any time we run into a DocuWare editing anomaly.
So, any ideas on what other people are running into? Can you replocate this issue with your PDF editor of choice by chance?
