Touchpad multi-finger scroll issue changing screen

Hi,

I recently purchase an XPS 9510 15 inch and have been having issues with the touchpad and scrolling.  Two-finger scrolling often activates the three-finger scrolling action of changing screens.  At first I thought it was just me touching the touchpad with my palm or something, but this definitely isn't the case.  It doesn't always happen, but it extremely frustrating.

Any advice? I've only had the laptop 2 weeks.

Thanks
