PDFs corrupted by PDF Commenting

[Fei Min Lorente]

Joseph said he enabled PDFs for commenting in acrobat reader 3. I
thought you couldn't comment on PDF files using any version of reader
older than version 7?

One of my clients reported the same problem. Reverting to Adobe Reader 8
for reviews seemed to solve the problem.

An immediate workaround when someone comes across this problem is as
follows:
1. Do not close the corrupt PDF
2. Export comments by selecting Acrobat Comments > Export Comment to
Data File
     (the exported comments (fdf file) can also be sent to you) 3.
Re-open the original file and save with a different name 4. Import the
comments into the new copy by selecting Comments > Import comments.
5. Save the file.

It is possible that this problem is also related to the way Acrobat
saves changes to a PDF. Essentially, all changes are accumulated in a
way that does not remove editing history ("incremental save"). Using the
"Save As" 
function, overwriting the same name, removes all editing history and
rewrites the entire file (which is why "Save As" is slower than "Save").
I recommend that your editors do a "Save As" once in a while -- you may
find that this alone will resolve the problem.

Please share your results, as this is an issue that other uses have
encountered.
