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 At 10:37 25.11.2003, Hans wrote:

Looks like an acrobat bug to me; if you use gsview, it works ok; there are more problems with acrobat and transparencies, like
- no smoothing when a vector graphic is on top of a transparency - disappearing characters (esp very big ones) - funny flattener preview colors
One of the reasons for such problems is that there is no 'reset graphics state' operator and i guess that occasionally the acrobat graphic state stack gets messed up.
