I got it,
at least I can work again with my system. I insalled an old Miktex 2.4 and now
it works again. I still have no clue why (on my system) it doesn't work properly
with Miktex 2.5 but I won't touch anything for the next ten years!
(The only thing which is a bit strange, that on my lyx 136 in the view-menu the
"pdf" is gone, there is only the "dvipdfm" and the "pdflatex". Is there any
possibility to change that. (in the export-menu there is still the pdf which
uses the ps2pdf...)

Robert
