I'm a brand new AA1 owner, loving the heck out of my little machine, except for one little thing that's driving me crazy. The cursor pointer loves to hop skip and jump all over the screen. I've adjusted the sensitivity of the touchpad thinking that that might help, but it has only helped a very little bit. When I plug an external mouse into one of the USB ports, the problem seems to go away. Are there any other adjustments that I can make that may solve this problem, or will i have to return it for repair or replacement? Any informatrion will be greatly appreciated. Many thanks in advance. AJC :)
