Chaps,
I know we all get a bit focussed at times. However, the forum really isn't the place to get agitated .. if a question is asked, one should presume that an answer is desired. If the question surprises one, that is fine .. but the need is to answer the question rather than chastise the person asking ..
As always, play the ball rather than the player (and I had to give some thought as to whether I should add that comment ... c'est la vie).
