Hi guys. I have noticed why I feel sometimes the touchpad (on an otherwise near perfect SP4 Type cover) is a little unresponsive. I must move my finger about 5 mm before it first registers movement. Once triggered, I can move my hand by less than 5 mm, and it works fine, so it's definitely not a problem with sensitivity. My Surface pro 4 is completely up to date. Is this something everyone has, and is it something that can be corrected? It's quite a nuisance when dealing with small GUI's.
