Why do the trackpad hand gestures suddenly stop working?

[petrucci666]

I restarted my MBP to install some updates and when I started working on it again I noticed that the trackpad gestures had stopped responding. This has happened to me before but I have no idea why. I know that when I reboot it again, that they will start working again, but it's annoying to restart everytime the gestures stop working.

Anyone have any idea why this is so?

Thanks

Maybe you can re-enable it in System Preferences as well?
