[tesseract-ocr] Tesseract problem with .bmp files

[Powniiiiii]

Tesseract finds '8' in im1.bmp and returns ' ' (blank, 0x20)
for im2.bmp.
2 online ocrs find '8' in im2.bmp.
Why, any ideas, something wrong?
Config: Windows 8.1, tesseract 3.02 portable,
call: "tesseract im1/2.bmp test -psm 10", no change with 'digits',
image files generated by c-program.
