My Laptop, Gateway,Mx6421. Is equipped with a Synaptics Pointing System for the touch pad. Every once in awhile I'll hear a "whooos" sound and lose my scrolling capabilities. I can still point and click, but can't scroll pages or shift right to left or left to right. I can correct the problem by clicking on the icon for the system, the clicking on the field of the desktop. Its no big deal, but it would be nice if I didn't have to do this. Any ideas, wrong settings or ? Thanks for any help....Dennis
