I am not sure why the software hangs, when, trying to scan over USB from HP OfficeJet 5610, and, I am only able to terminate the underlying processes through Task Manager.
Usually I just restart the laptop (or log off and log on again) to ensure any startup programs are re-run, however, sometimes, the program simply hangs during the scanning process, or, when I select Cancel, and, the screen indicates 'Cancelling'. The program sleeps in a cancelling state for over 5 minutes, and, does not seem to release the resources effectively.
It has also been noticed that although I cancelled a scan after I cancelled it, the program actually left a scanned image in the expected 'My Scans' sub-folder, at some point, however I might be mistaken in this, because there were a myriad of processes running on the laptop.
Great Game Play
