Is there a recommended way to use a ProPoint on the empty space on a laptop (i.e. to the right of the touchpad) when this area isn't smooth (it's hard to move the mouse across this surface)? I've had a number of pen grip mice, and the old ones came with a large "sticker" that could be placed on the laptop, and this was a great surface for moving the mouse on. But the newer pengrip mice haven't come with this.
