Hello, I have a Dell D620 laptop and recently I have been having trouble with the input the tells the cursor where to go. I have the standard finger-pad that I use to move the cursor but there is also a little blue rubber thing between the "h" and the "g" on my keyboard that can also move the cursor. Recently, while I have been typing, when I press the keys close to the blue thing, it actually gives it enough vibration so the blue thing thinks I touched it and it moves the cursor away from where I am typing. This is really annoying because then the text starts showing up in the new location. Does that make sense? Does anyone know how to turn the little blue thing off or make it less sensitive?
