Time after time

There is a teacher in the school who has asked me on 5 separate occasions to install a particular piece of software ASAP on a computer because she expected it to be there already and couldn’t find it when she needed it.

Each time it is a different computer. Each time, the software is already installed, complete with a shortcut in the same place on the Start Menu as on every other computer.

I might be able to understand this if a) the shortcut was not in an obvious place, and b) this had only happened once or twice, but after 5 times of the shortcut being in a place that everyone else in the department has no trouble finding, I’m starting to wonder if she has genuine memory problems, or if she is just an idiot.
