Cursor jumping while typing - Windows 7

[Kruzen]

Your palms are very very very slightly touching the capacitive touchpad.

Plug in an external keyboard and I guarantee you you will never see it happen again. I do it all the time and it drives me bonkers

edit: You may be able to disable your touchpad while and external pointing device is plugged in as well, ala http://labnol.blogspot.com/2007/05/d...top-avoid.html

Ok, this is driving me fucking bonkers. Ever since I switched to Windows 7, my computer has been doing this thing where when I'm typing in a text field (in either Chrome or FF), after a few words, my cursor will just jump to somewhere else on the page and start typing there, or I will start typing random keyboard shortcuts that close windows, take me back to pages, etc. I have no idea what is causing it, and it's making me insane.

I'm on a Dell laptop with fresh install of Windows 7 Pro, using mainly FF. Is it possibly some kind of keyboard or trackpad driver that didn't get installed that is making the cursor jump around? I NEVER use the trackpad, I always have a mouse.
