Hello Leonard,
I do mean "Adobe Reader XI" on 32-bit Windows XP. I'm not editing the
PDF, exactly. Let me provide an example.
The IRS provides a four-page PDF for the "941" report, and a second
report (addenda) called the "Schedule B". Only two pages of the 941 have
actual "pdf form" data.
My program will create a new (empty) PDF, open the 941, splice in two
of the four pages, splice in the Schedule B (if needed), and then fill in
the form fields with the proper data. I must also embed another font and
create an appearance stream (you helped me with this logic a few years
ago). The software will then save the PDF.
If I open this PDF in Adobe Reader, it looked correct (form fields are
filled in). However, if I attempt to exit/close Adobe Reader, it prompts
me "Do you want to save changes to XXX.pdf before closing?" (even if I
changed nothing while Adobe Reader was open). If I decline, then Adobe
Reader exits and nothing special happens. If I elect to "save my changes",
then the resulting PDF on disk is smaller then the original, a new
top-level section called "/Metadata" is created, and the "/Acroform" is
altered. I have yet to determine what gets removed from the PDF that makes
it smaller, but I suspect that it is the font that I had to add earlier.
If I don't add that font, then the fields that I filled in are not visible
in Adobe Reader unless the individual field is selected by the user (input
focus).
I can repeat the above with the other forms that my software will
populate (Arizona A1-QRT and Arizona UC-018).
(Federal 941 report, file size difference is not much)

(AZ UC-018 report, size difference is significant)
