Disable touchpad switch application?

When i'm scrolling sometimes ubuntu will think i'm trying to switch applications.

Is there a three finger application switching feature in ubuntu 13.04 that i don't know about?

It sometimes also switches applications when my palms are touching. I tried disable while typing and it's not optimal or user friendly. It's rather annoying to me.

Solution 1:

Yes. This is three finger tap followed by hold to switch between app windows. The explanation here. https://wiki.ubuntu.com/Multitouch

Solution 2:

In my case, running following command solved the problem.

synclient ClickFinger3=2
