Then I got the drivers and configured to Nuance. Also some nuisance items, like the invisibility of the Menu toolbar because the text color and menu-bar color are the same.
You have to run the mouse across the screen and 'File,' 'Edit' and 'View' show as gray on blue. So Corel needs configuration to 'Acquire Source' or the scanner. Started with TWAIN - no go - scanner unresponsive.
