I noticed one more thing. In the control panel if you select hardware & sound and then mouse and then elan.
In the elan selection there is a button labeled "disabled when external USB pointing device is plug in".
When that is checked the screen seems more likey to mis-behave so I now leave that unchecked and then press F6 when I open the lid to disable elan as I prefer a mouse to it.
