I saved a pdf as tiffs out of Acrobat Pro so that Microsoft Document
Imaging could OCR it for me, and it reads the first page as if it were
upside down. Whether OCRed as part of the ten-page set, or as a single
page. When I tried rotating the image, so it appeared upside down in
the MDI window, it also read it as if it were upside down. And after I
OCRed the individual page right side up, it flipped the view to upside
down when it was done!
