I attached the final pdf and a screenshot out of acrobat viewer (v7.08,
Win XP) at 300%. If you zoom the screenshot at the top/right edges of
the clipped boxes, you can clearly see that there is something wrong.
Maybe a viewer problem, as 'foxit reader' shows the same glitches at
lower zoomlevel, but not at higher zoomlevel. Acrobat Viewer shows them
even at 6400%. Mhh, I will test this on another computer.

Thanks anyway,

Peter
