Hallo you all.

I found a strange problem. I create my slides with ConTeXt. Everything was
all right before I included pictures in PNG with transparent background.
Adobe Reader 8.1.2 under Linux (at least this one) changes colors on every
page where such a PNG is included. Xpdf shows it all right. I wonder what
could be the reason, and how to solve it. Can you hint me?

You can see the behavior here:

Notice difference in colors between the 2nd and 3rd page (the 3rd one
includes PNG).

PNG are created with Gimp.
My ConTeXt is ver: 2008.01.28 21:28 MKII
pdfTeX is 3.141592-1.40.3 (Web2C 7.5.6)
TeXExec is version 6.2.0
All under openSuSE Linux 10.3.

When I start TeXExec, I got this warning:
  /usr/bin/texmfstart:1838: warning: Insecure world writable dir
/home/qasar/bin in PATH, mode 040777
  /usr/share/texmf/scripts/context/ruby/base/system.rb:16: warning: Insecure
world writable dir /home/qasar/bin in PATH, mode 040777
But I guess it has nothing to do with the color problem.

Many greetings to all of you, and thanks to those answering me. ;-)
Have a nice day.
M.K.
