Apologies if this had already been discussed and I missed it in search. If I put my finger on my Surface Pro 3 type cover and try and quickly move the mouse pointer just slightly, the pointer doesn't move at all. Larger movements respond immediately. If I hold my finger on the touchpad for a slight amount of time and then move my finger just slightly, it seems more responsive. I find myself quite frustrated with this but I see nobody else complaining. It would be great if my type cover is simply defective but I fear otherwise. Thanks.
