My mouse pointer frequently vanishes on my new MBP. I then move my fingers off the keyboard and trackpad and move a finger around the trackpad till it re-appears. This takes longer than I'd expect to find it again. How to 1) Prevent it from disappearing to begin with? 2) Find it faster? I did go into Accessibility to change the mouse pointer to the fat one with the outline, in case I just wasn't seeing it. But that's not it.
