Thanks to all who posted, sorry I haven't responded earlier but even now I'm typing this virtually one eyed as I have just had extensive laser surgery to my left (dominant) eye and am viewing the world through a thick lace curtain. I'm told it will take several days to clear back to normal, but I take that with a pinch of salt as I have never been 'normal' in my life. Ha ha.
Hope to catch up with the world of Mudcat next week.
