Saving a PDF causes the document to be considered modified, even if there were no changes made by the user.
Since the document appears to have been modified, MacroView UDN/AOI performs a Check-In Overwrite Version. This causes the modified date to change but keep the version number.
Can it be avoided?
It's not possible to determine the reason the document was modified (e.g. Save As PDF v.s. Ctrl + S), so we can't add logic to detect the Save As PDF (or other file type) scenario.
Additionally, there might have been actual changes made before saving as PDF, in which case we want to commit these changes and overwrite the version.
