strange, because my version accepts this; is this a linux problem?

anyway, in cont-sys.tex you can say:

\maxnofMPgraphics = 4000

if this problem is persistent, i can default to 4000 (and set it to 8000 here)

The count up-down has a reason: graphics generated during typesetting the 
pagebody don't influence the text flow; by using a different range (count 
down) a change mid document of a graphic that is part of the background 
(say, that you add one), will now have no
influence on the page breaks (due to a possible change in order, and 
thereby swapping of graphics); this can save many runs as well as 
oscillating [i hope you understand the problem, it's hard to explain]

imagine (--automp):

page one : text graphic + background graphic
page two : text graphic + background graphic

first  run: no graphics
second run: text graphic 1, page grows, graphic 2 moved to page 3
third run: extra background graphic, old background graphic takes place of 
text graphic

etc etc; pretty tricky but it works quite well now (you cannot imagine on 
what weird things i spent my time)

I don't know, can you make a minimal example showing the problem? Maybe 
solved already. (time to post a new beta)
