What a load of bickering!!, it's like a junior schools playground!!
some apologies, but practically no useful input, either converse in a sensible manner, or else either Mark or I will kill this thread by closing it, if that's what you want, say so, it can be done by the click of a button.
Right, I have made up my mind to close this thread, reason?, I think it was a weak decision to start it, & it has rapidly developed into wrangling, serving no useful purpose.
