Hi Brian,

Compare your current EnTwain unit with the one from version 2. The "if not PendingTransfers then" statement should stop the loop.

I think I recall seeing some twain interfaces, where you need to close the interface after scanning to return to the application.

Also, make sure you test this when running your program outside the IDE. I have seen strange results scanning within the debugger.

Best regards,
