Is this really true?  or is it a problem unique to windows. On Linux I regularly
run archived TeX files from a CD because there is no reason why the
TeX source file should not be read-only.  But the directory/folder in which
I work must be writable.  A link to the read only file gets around the
default behaviour of TeX that it wishes to write to the same directory/folder
as the source file.  But maybe WinXP notions of linking are still too primitive
for that
