Multitouch gestures and Hot Corners just stop working out of the blue

Like the title says, they just stop working for some reason and then I have to restart the computer.

On a 2012 MBA with Mavericks installed.

Anyone else experiencing this problem?

Possibly try a SMC reset.

Thanks, I gave it a shot and will see if it happens again.
