Hi,

Indeed there was upon a time such a discussion ... Though not 
remembering the details, I found a test file and after a small 
adaptation it gives two pages:
- first page: page-background green (as defined by Context)
- second page: page-background as the first page, text area gets a 
transparent color with the values "normal, 0.5, white".

The result in Acrobat Reader 7 is indeed not to expectation. The page 
backround on the second page is still green, though not at all of the 
same colour.

Apparently there is no mistake in the pdftex-PDF-file because viewing 
this file with Acrobat 5 (!) the result is as expected. The 
page-background remains the same green on both pages.

Kind regards Willi
