well, it tends to happen to me sometimes, because of the touchpad. When you type, your thumbs may be above the mouse area of yoru laptop and if you go to near, the laptop may register it as a click and move your cursor in some random places. In general, good touchpad drivers have an option to disable the pad for a small delay when a key was pressed, to avoid that problem (never understood why it was not activated by default though).
