[OS X TeX] Leo.1 and cgpdftops -- something has changed

[RA Friedrich Vosberg]

Morning.

Obviously Apple has changed something concerning the creation and  
display of PDF files when using TeXShop. In 10.5 the PDF files were  
displayed correctly but TeXShop has crashed when trying to print such  
a file.

Now in 10.5.1 the old style numbers are displayed in a Helvetica  
narrow style font. The PDF file isn't printable, the printer ignores  
the file, but nothing crashes. Adobe reader displays and prints  
correctly Mathpazo old style numbers in the PDF file.

The most curious is: When I typeset a file like
   \documentclass{ltxdoc}
   \begin{document}
   Test
   \end{document}

TeXShop doesn't typeset it in the normal CM font, but in a font like  
Helvetica Narrow.

What's wrong?

TIA and kind regards, Friedrich
