Hi Grandfather, please dont take offence. It was an off-the-cuff comment. I write as I speak; with a sarcastic, jocular tone that can't be heard on a forum board and tend to over exaggerate for a bit of artistic flare! I'm grateful for your help, I was specific in writing thanks for your replies (plural) even though I did not reply directly to you. Genuinely, your help is appreciated and your advice sound. Thanks again. :)
