Unfortunately, none of these solutions have worked properly for me.
I'm a professional graphic artist who's used Wacom tablets for almost 20 years. I thought the Surface Pro would be the perfect tablet for me, but after spending over £1000, I found that it is virtually useless due to it not supporting the hovering right click on it's pen (like Wacom).
My Surface Pro 4 is now sitting on a shelf as is a useless machine to me, apart from the occasional web browsing!!! I now have to look to buy the Wacom Cintiq graphics tablet.
Microsoft had the almost perfect machine, and it has been crippled by it's poor choice on pen driver software. A update fix could sort this, but after 2 years MS have not listened to anyone in these forums.
