I suffered with the problem of a jumping cursor on my new Dell Latitude e7440 Ultrabook for 5 months before finally finding this forum and reading that this is a common problem with newer Dell computers.
I have used Dells for about 15 years and never had this problem with their prior laptops, but had it from the start with this Ultrabook. When I am typing, the cursor skips to some other place on the page than where I am typing, causing me to type in the wrong area.
I solved the problem by installing this touchpad driver:

After the above driver was installed, I did this:
Double-click on the touchpad icon on bottom right of the screen (looks like a PC screen to me).
Click on “Tapping” (top right)
Uncheck Tap to Click
Click on “Back”
Pointer speed: Set to about 70% of the way to the right.
Touchguard (on bottom):
Click the “Turn On” box to enable Touchguard
Set Touchguard to half way.
Tradeoff: The further to the right you set the Touchguard, the more the touchpad will be suppressed during typing, but the longer it will take the touchpad cursor to appear/respond/move when you ask it to do so after typing something. 50% of the way to the right (i.e. in the middle) seems to work well.
Finally, after 5 months of agony with the jumping cursor problem, I have relief. The cursor does not jump around at all when I am typing now.
