Although I am personally very fond of the new PDF Reader v8 from Adobe, there is a small bug that occurs with transparent objects that can causes some of output to not display. Adobe has been informed, and they are working on it.

    Fortunately, this does not affect PDF reDirect at all. PDF files generated using PDF reDirect Pro can be affected, but only if you use the watermark feature (that is, a stamp that stretches accross the entire page), and only if you use more than one stamp.

    Hopefully, this will be fixed when the new version of PDF Reader v8 comes out.

Here is a screenshot that shows the problem [here].
