No Additional popup into a new window when saving a project summary PDF.

D-Tools SI automatically opens Adobe Acrobat every time I export a report to PDF. I do not want the exported PDF to open automatically. Acrobat's automatic-open settings are all disabled, and the behavior occurs whether I export to the Project Folder or use Select a Folder. Is there an undocumented setting, registry value, or configuration option in SI to disable opening the PDF after export?
