Since a couple of days, my computer mouse has started behaving erratically. It works fine, then suddenly stops working. To make it work again, I need to disconnect the mouse and connect it again. I am fed up.

The more important problem is that operating Windows has become almost impossible. By using the mouse, not only operating the keyboard a little unfamiliar, but it is downright cumbersome. Additionally, there are many areas of the computer that seem to be out of bounds. For example, how to get the menu for applications that are in the task bar?

Many years ago, things we manageable without a mouse – when I used DOS or command-line Unix. Now, operating a computer without one is very difficult.
