Hi Hans,
Indeed now I tried in Acrobat5 and the problem does not show up.
There is probably another bug to be reported:
I got a file, where with \startcombination ... \stopcombination two small
pictures are placed next to each other. - When viewing the result in
Acrobat6 everything looks ok. When printing the page, then the right
picture will not show up on the print!
Kind regards Willi
