A senior manager once called me over to sort out a "virus" on his PC. Whatever he typed in his document immediately scrolled up and off the top the window. He was in a bit of a panic. There was an open ring binder folder on his desk and I slid it forward slightly, so that its corner was no longer pressing the space bar. "Should be okay now", I said.
I tried to joke about the "magic touch" but had to tell him in the end.
