I have some reservations about changethis.com's stance on
document presentation, and no way of knowing where "fault" lies
in this case, but notice that the below symptom does not
appear with gpdf or Acrobat reader. This problem is either an
xpdf bug (which is worth reporting on its own merit) or with
changethis.com and the other viewers (in which case
bug-compatibility with other viewers is probably still worth
pursuing).

If you view essentially any of changethis.com's manifestos (e.g. [1])
a box titled "GO AHEAD AND PRINT THIS" appears over the document
text.

Thanks for the report. I see what you mean even in 3.01-1, so I'll
forward it upstream.

The document looks quite trashed in gpdf, which is based on xpdf 3.00,
so I'm surprised you got even that far :-| On AcroRead 6 on Windows the
document insists on running full screen so they are probably being evil
in the document.

Hi Derek,
Interesting report, possibly of an unimplemented PDF feature.
Confirmed in 3.01.

There are a couple different issues there (all missing features in
Xpdf):

* the overlay box is an annotation, which is marked as hidden - Xpdf
  doesn't currently look at the annotation flags (including the "hidden"
  flag)

* the overlay box uses transparency, which is not fully implemented in
  Xpdf

* that PDF file uses an interactive form (among other things, when you
  roll the mouse over the print icon, it un-hides that annotation)

All three of those are in the queue of things to be worked on.
