ah for the t#echnical side of things and thank god for the punctuation side of things. but do you know if any body else can understand you ,if you have got degrees an all that it's easy but us down to earth people dont' understand a word you are saying so what good is that no help at all so you are wasting your time answering the question .You so called boffins i was teaching an old lady to use a computor she wanted to copy a file and i said right click the file and select copy ,she sat at the computor and typed CLICK. There are still people out there that do not understand COMPUTORS ,put your feet back on the ground and listen to someone else for a change
