Error: This page has graphics other than images or text on it

Question

I recently upgraded to Adobe Acrobat 9 Pro, and I am experiencing a problem
with OCR text recognition.
If I use "Create PDF from Scanner" or "Create PDF from file" (using a
monochrome TIFF image) to create a PDF, I can then perform OCR on the PDF
file in Acrobat.
But if I open a monochrome TIFF image in some other program (Irfanview) and
print that to the Adobe PDF printer, then open that PDF in Acrobat and try
to perform OCR on it, I get the following message:
"Acrobat could not perform recognition (OCR) on this page because: This page
has graphics other than images or text on it. It cannot be captured."
If I select the scanned image in the PDF file using the TouchUp Object tool,
and then cut it to the clipboard, I am then able to then select a second
blank object on the page, that has the same dimensions as the scan (it is
full page size). If I delete that object, then paste the first one back in
(the scanned image), then OCR will work. So what is this additional object
that is preventing OCR? I did not have this issue with versions 4-8 of
Acrobat.
Also, this problem appears to only pertain to 1-bit monochrome images. I
scanned the same page to 8-bit grayscale, then printed that to Adobe PDF
from Irfanview, and that PDF file allows OCR to be performed. Does anyone
else have a problem using OCR when the PDF was created by printing a
monochrome raster image to PDF?

Not sure this will work for indesign, but for any other searches about the OCR problem with "This page has graphics other than images or text on it", I used this workaround for a huge scanned text that Acrobat 9 Pro wouldn't OCR:
1. Save As.... > TIFF image
This saved each page as a tiff, so if your file is big, you might want to create a special folder for it. (I had 1100 pages!)
2. Open the folder with the TIFF images.
3. Select all files.
4. Right-click > Open with.... > Choose.... > Other.... > Acrobat
5. Popup will ask if you want to open all files in a single document. Obviously a good choice for 1100 pages.
6. After the new PDF generates, save it.
7. Document > OCR --- should work now.
8. If it does, don't forget to delete the folders with the TIFFs.
Hope that helps someone.
