Font problem

[Maxime Brugidou]

Hello
i installed lilypond with cygwin on my winXP and are now able to use 
lilypond
i can do really good sheets but i can't add text
i think there is a problem of font : the text is printed with some 
dynamic letters (such as f or m or p)
so some letters are not printed ...
i even tried to generate a pdf with examples of .ly files on the website 
tutorial, but the pb is the same ...
(i know i should use debian, but for the moment i'm with windows)
what should i do ?
(i hope this is the good mailing list for this kind of pb)
