I got a problem: after I open gscan2pdf an info window appears saying:Save as DjVu requires djvulibre-binunpaper missingOCR requires gocr, tesseract, ocropus, or cuneiformafter I close that window the little progress bar then runs back and forth as it is "opening device". Then an info window appears saying, :"Error opening device: Invalid argument"It was working. It was doing this with gscan2pdf version 1.2.3 (the apt version) so I updated it to version 1.2.6 but it was still doing it. I googled 'gscan2pdf "Error opening device: Invalid argument"' but their were only 4 results. The only one of which might have helped said to:rm ~/user/.gscan2pdfrm: cannot remove ‘/home/bmike1/user/.gscan2pdf’: No such file ordirectoryI then ran apt-get for the programs it said were missing and now only the "Error opening device: Invalid argument" info window appears.Any ideas as to how to resolve this?:-)~MIKE~(-:
