I always show how one of my paintings has been put together on the Electronic Sketchbook, when visitors come on one of my tours. (remember those?!)
I have four paintings on the screen and when I click on one , it automatically shows images of my trial studies, early observational drawings and artists references.
A few months ago I noticed that the icon to start the sketchbook had disappeared. Although I saw it fleetingly when I switched the computer on it always vanished before I could do anything.
My daughter and her family finally came to visit us for a day over Easter. My son-in-law, who works with computers agreed to have a look. Within a few minutes he had found the icon lurking under the surface. Hurrah!
