I just upgraded to the latest version 1.7.3. The software is not working correctly anymore. I open PDFCreator and click the Printer stop button. When I drag a file into the program it gives me the warning about setting default printer to PDF which I say OK to. But then instead of waiting for me to click the Print button it automatically prints whatever file I dropped to the default printer in my office, not to the PDF printer.
So as far as I can see the Stop Printing feature that allows multiple files at once is not working. And it's not setting the default printer to PDF as it should be. These worked fine for me on previous 1.5 version. I am using Windows 7 64 bit.
