I got so confused today I was talking to someone in my office and my machine went mad. Windows changing, words appearing on screen and general weirdness.

Turns out that though I'd paused my Windows Media Player I'd forgotten to mute the mic on my headset so Vista Speech Recognition was trying it's hardest to keep up with half heard instructions and dictation.

It was only when I saw the cool numbers appearing on anything clickable on the page with focus I realized what was doing it and hit mute quick smart

Luckily I didn't send a rant to BillG about how the vending machines needed more chocolate ;)
