Ok, I will try to describe. I use the following version: PPower4 version 0.8.x-SP-beta5 Copyright (C) 1999, 2000 Klaus Guntermann, FG SP, TU Darmstadt PPower4 is free software; see the source for copying conditions.

I use esopic. When I add things to the ShipoutPicture with some pauses in it, when there are more levels on this page than on the preceding page, I get the following error message from Acrobat: There was an error processing a page. There was a problem reading this document (14). And the last level of the preceding page (Here, it is some bit of mathematics) appears, and disappears after accepting the error. This doesn't depend of the thing added. Just pauses in shipoutpicture. Any hint ?
