I do not want to make comparisons
the changes where the number of pages I want to see
underline the changed text, then find and print the underline text.
If you know where the changes are the puzzle is resolved.
And the thread is looking for corrected pages in a last session that were not marked and cannot be easily been checked.
What Handifem is not noticing is that comparison is (perhaps) the main tool to find differences between things...
The idea behind using Kasyan's script is NOT exactly checking the detailed changes between two pages in different stages of proofing..
And the happy thing is that this script tells which pages do have changes.
This information is enough to solve the problem.
Another method is comparing (again) two PDF made off with the last two versions.
The result of this test shows fastly in a report which pages changed.
Another one! Export the same last two versions (if they are very similar...) as RTF text and in Word make the comparison.
Fortunately, this word processor is very effective doing this test.
