It seems even Steve Jobs isn't immune to bugs and errors on the an Operating System when he demonstrated the latest Operating System for the Apple Mac due later this year.

Jobs was performing a live demo of a new search tool within Apple OS X Tiger called Spotlight. When the machine didn't response the CEO of the computer company quipped

“It seems we have a bug here”

Unlike Bill Gates' recent bug experience, however Jobs was prepared and immediately switched to a back-up system that was already running.

Later on in the Keynote speech Jobs was showing a new widget that allows you to run live stock feeds in the background alongside other applications.

The Live Stock tracker demo showed Apple stock down's down to which jobs retorted

“well we've still got a lot of the keynote to go.”
