That would not help other R users who were looking in the archives for
help with what looked like a mysterious normalizePath error, would it?

As I said, the principal intent of the posting was to point to a
possible work-round for other R users - i.e. temporarily disabling
on-access scanning in the antivirus package. 

But that would have been better posted to R-help, so it's now cc'd there
with the original posting below in case anyone else out there can use
the tip.
