Cursor jump to other location while typing on Ubuntu

Disable mouse clicks with touchpad

I am using Ubuntu 9.04 for my Dell Vostro 1400 laptop, and faced a very annoying problem where the cursor jump to other location - probably to the location of mouse arrow - while I am typing.

How do I solve this problem?

What I do is, I disable the "Enable mouse click with touchpad" in the "Mouse Preferences" dialog box.

To bring up the "Mouse Preferences" dialog, click on System > Preferences > Mouse.
