Witchcraft?
Back in the 1990s I was working in a sixth form college. The science department had a number of Acorn Archimedes and I was called out one day to one where the mouse was behaving oddly. I knew those things had an optical mouse that wasn't light-tight and as soon as I went in to the room I noticed that the whole desk was in bright sunlight.
So I moved slightly so that I was casting a shadow over the mouse (and still a good ten feet away from it) an said 'I think you'll find it's all right now'. The lecturer's face was a picture as he tried to work out what I'd done!
I had to tell him, so that he could relocate the desk out of the sun...
