Yep, well, I am using 

\startbackground Some stuff \stopbackground

The backgound crosses the page-size:

+-----------------+  --> text boundary
|                 |
|   +---------+   |  --> Backgound edges
|   |Some text|   |
|   |Some text|   |
|---+_________+---+

The background box is a bit deeper then the page-boundary (Sorry, I 
mean the \zethoogte).

If you need more info, I can send you the resulting .pdf file which 
shows these difficulties (I will not post it on the list). I can also 
send you the style file I use, but it is **very* similar to s-pre-01

This is *very* cool (I don't need it right now, but I'll keep it in 
mind.

The \leavevmode was necessary to make consecutive empty lines show 
up too (normally they are handled like multiple \par, e.g. they are 
changed into a single \par.

Dat komt later. Die #1 wordt later:

  \naar[#1::]{Echter poster}

  where #1.pdf --> poster file of the destination

> Why the obeylines? 

Because the people who wrote the input file needed some basic formatting 
control (simply some newlines will suffice for them).
