There seems to be no way to adjust touch pad on dell laptop. It's real sensitive, but there isn't an icon for it in the notification taskbar, nor is there anything in the control panel under mouse. It's very distracting because programs disappear and other programs just open up willy nilly.
Make sure none of the system-tray icons are "hidden".
If there is a little arrow-head at the left-hand end of the tray, click-it to reveal hidden icons.
