My computer behaved very strangely this morning. The wheel on the mouse didn’t scroll up and down; it made the text on my browser bigger and smaller. When I tried to type things, I got all kinds of bizarre results. What’s worse, when I switched to the keyboard and glide pad on the computer (I prefer to use a wireless keyboard and wireless mouse peripheral) it continued. Disconnecting the keyboard didn’t solve the problem right away, but after about five seconds, it did.
Turns out, my “CTRL” key was held down for some reason. It still feel a little bit sticky. I just cleaned the keyboard out with one of those compressed-air dingies so I have no idea why it should act that way.
