OK thanks for the good tips,
I really tried hard and finally succeded in a certain way.
First off all sorry Herbert but the linebreaks in the e-mails I can't change.
I now installed gs_6.01 (which is quite a hard work for a non-programmer) and the pdf
files are nicely small. Also the text charakters are looking good. Is it really not
recomendable to use the latest gs_7.0 or the gs_6.5?
There is one strange thing left. When I export the document from Lyx to a ps-file and
then do ps2pdf all the minus symbols from math mode are gone?? When I export from Lyx
a DVI-file and then do "dvips -Ppdf" and after that ps2pdf everything seems to be OK.
So my question is how can I specifie this "-Ppdf" inside Lyx?
Sorry but thats all really "nebul�s" for me.
Thanks
Wolfgang
