Would it be possible for you to supply our TWAIN engineers with a log file captured immediately after the hang occurs? The PSIP log file generator is fiInfoCollect. Before running your app, run fiInfoCollect. When the error occurs you will need to click the “collect” button. Record the time of the error as well as any relevant info such as what was being attempted at the time of the error. It helps in reviewing the log files.

I’m having the same issue with the same scanner and TWAIN version.
