Hi Cutponies and Trouble, you've given me much to think about. I will experiment, though I'm not sure if Roxio does all that you both recommend.
But there could be a problem with scanning in B&W as I draw with a handwriting pen, and I found B&W scans were unsatisfactory. But I didn't experiment with B&W, so I'll look at this first.

Thanks very much for your assistance!
