Apologies to the three people who saw my latest blog post on this site today. I didn't realise that I'd clicked the wrong blog in my list to post to. When I saved it, then looked to see if it was OK. It had gone, not even a draft version was there. Two hours work lost. A short while later I decided to look again. The first site which comes up on my blog list is this one. To my horror, I saw my "lost" graphics post was there. I've deleted it of course, and it's now on my own site. Sorry about this, blame it on old age.
