PDFCreator does not open the last saved location by default, as both 2.5.3 did and as it states it should in the user manual. Please see below for the wording from the manual.
Thank you for logging it and also the update
Just experience today the same issue having to create a couple of manual Invoice PDF’s to be emailed to clients.
For anyone coming to this thread later, this issue appears to have been resolved in PDFCreator 3.0.2, released on 2017-10-11. While I’m disappointed with the lack of anyone messaging me the resolution, the change log for the new version did note that this issue was resolved. I tested the installation and it is working appropriately. Thank you for your help.
