Of course not. Perhaps I should have paid more attention to this 
particular case and less to general principles. But what I wrote was, I 
think, the rational explanation. We are, however, dealing here with a 
bug and  bugs are like acts of God (and I don't mean Stephen W.) which 
defy rationality, at least as far as mortals like myself are concerned.
