[XeTeX] XeTeX and Vista

[Arno Trautmann]

Hi,

I’m new to XeTeX and was very happy with it on linux. But now I am 
doomed to work with Windows Vista – and, as expected, it doesn‘t act as 
it should. XeTeX works fine with an simple example as

--
test

\bye
--

I get the pdf-output and everything is fine. But trying to use a font like

--
\font\myfont="DS-Garamont" at 14pt

test
\bye
--

causes XeTeX to stop (not any output) and holding nearly 50% of CPU.
I have MikTeX 2.7, Windows Vista.
Is this a known bug? Is it my fault, is my code wrong? (With linux I got 
what I wanted) Any idea, what I could do? I guess, Vista doesn‘t allow 
XeTeX to access the font folder, but I don‘t know neither Vista nor 
XeTeX good enough to solve this.
I would be very happy, if anyone could give me a hint how to fix this.

Thanks,
Arno
