No idea if you're still looking for the answer to this, but if anyone searches this question, hopefully they will find my answer!
Click on the little up arrow on the right hand side of your start menu (your open applications), right click on the little icon that looks like a touch pad (large rectangle on top of 2 smaller rectangles). Select TouchPad properties. Navigate to the Device Settings tab. Select your touch pad device and click settings. Select the "tapping" subcategory. Unclick "enable tapping".
There, done.
