"HalfTone" works with "GrayMap" files", not with the normal "ScanImage"
documents.  "GrayMap" files are created by holding down the Option key while
re-halftoning a selected area.  Details of this process are found on page
4-30 of the 'new' manual.  Unfortunately, there is a bug in the ThunderScan
software which distorts the image in these files.  Documents scanned at 100%
look OK, but other magnifications get stretched.

I hope this helps.
