Dear Mr. Ripley,

indeed that it true. sfInit() currently have a bug on Windows depending 
on the usage of the Linux tools and the broken Exceptionhandling. Too 
bad I never tested it accordingly on Windows (as we do not have any 
Windows machines in our institute).

snowfall 1.62 is in the pipe with many other fixes (e.g. NetWorkSpaces 
usage) and I will include a Windows workaround in it.

It will go out for testing at the beginning of the week and should be on 
CRAN end of the week.

Best regards, Jochen Knaus
