i see all correct but when i export to pdf image frame in which i load pdf are wrong because has wrong scale,
in preferences as the image i attach, if set to 72 all pdf in image frame when export are correct but i lost the high resolution view in document because is set to max 72 dpi!
so I come to the conclusion that in external tools and applications where there is postscript interpreter if I put the resolution over 72 dpi then when I export everything is wrong.
