Hello. When I try to combine several open files into a PDF by clicking on the combine files button in the main toolbar, or by going to the drop down menu, the dialogue box will not open. Instead, there is a grey shadow that appears in the center of the screen, where the dialogue should otherwise appear. Any advice on how to proceed would be appreciated!
