Grizzly,
sorry it wasn't directed at you but JACKC.
Just asked a genuine question in a polite manner and was insulted for my effort.
I'm normally not easily offended but feel I took the bait.
This kind of attitude can put some people off asking a question to which they don't know the answer for fear of being ridiculed or insulted. This in turn can lead them to carry out a task which could ultimately prove dangerous or they don't get something repaired/looked at which could be dangerous
BTW, thanks for the 'sonny' comment. Makes me feel young again!
