#871 Unable to scan more than one document in one session
I am using a Canon CanoScan 4400F and have found that starting with the 6.1.0 release of NAPS2, I am unable to scan more than one document in a given session of NAPS2. The first time I scan a document everything works fine and the scanned document appears in the GUI, but then the next time I click the "Scan" button to scan a new document (or the same document again as a test), the GUI "flickers" but nothing happens. Repeated clicks of the "Scan" button produce the same behavior. I am using the TWAIN driver and the "Twain Implementation" is set to "Default". I have tried all other TWAIN Implementations but the behavior is the same.
This behavior is reproducible under all 6.1.X versions. 5.8.2 is the most recent version to not exhibit this behavior. This is under Windows 10.
I am experiencing the exact same problem all of a sudden. Scans once. All other attempts cause the GUI to flicker and do nothing
