I just did, on our
 "Windows Server 2003 R2 \\ Standard x64 edition"

with

   > sessionInfo()
   R version 2.10.1 RC (2009-12-06 r50684)    i386-pc-mingw32

   locale:

   [1] LC_COLLATE=German_Switzerland.1252  LC_CTYPE=German_Switzerland.1252   
   [3] LC_MONETARY=German_Switzerland.1252 LC_NUMERIC=C                       
   [5] LC_TIME=German_Switzerland.1252    

   attached base packages:
   [1] stats     graphics  grDevices utils     datasets  methods   base
