Note, that these answers agreed with my independent conclusions as well.<br></div><div style="font-family:Arial;"><br></div><div style="font-family:Arial;">It is probably something silly that I have missed... but what it is I cannot tell.<br></div><div style="font-family:Arial;">Or is it a bug?<br></div><div style="font-family:Arial;"><br></div><div style="font-family:Arial;">Thanks,<br></div><div style="font-family:Arial;">Itay<br></div><div style="font-family:Arial;"><br></div><div style="font-family:Arial;"><br></div></body></html>
