I have the Imposition Wizard Standalone Icon on my Desktop and also the pdf-file.
If I open the Imposition Wizard Standalone and then File - Open PDF and I click Generate PDF, then the filename is on the Save PDF Document dialog include _Imposed.
If I click on the pdf-file and hold and drop it over the Imposition Wizard Icon, the Imposition Wizard is opening with the pdf-file. I click Generate PDF, then the filename is empty.
