Removed the checkbox for "Use Lockfile" to stop the "Save As" prompt in File \ Run \ PL_AdvancedOptions_ui.
(note: unselecting "Use Lockfile" could result in merged documents if users simultaneously use Sage 100 Paperless Office creating PDF files)
Bluebeam PDF from Revo will also generate a prompt to "Save As". In the Bluebeam Administrator there is a Printer tab, then in Printer Options there is a check box for (Prompt for File Name). Remove the check in the box, click Apply and Ok.
