I have a 2017 Surface Pro.
The touchpad cursor freezes every evening from about 5pm. I've tried
everything. When the cursor freezes, I generally have to use the touchscreen mode which never freezes - ever, but does not give you what you need for some kinds of work.
So for me it's def the touchpad that is the problem and it is when it is plugged in that the problem occurs.
It seems to me that MS must be working on this - it is not a one off clearly - it is an endemic fault with the Surface Pro. Not acceptable and given I use mine for work and for home use, I will have to move to another brand if this is not sorted - it seems
to have been going on since the Pro3 - we are now on the 7!
