I also have the identical problem. was online with microsoft to reinstall drivers etc...that worked for a bout 30 minutes. I was then told to return the surface for a new one, but from what I read here that doesn't solve the problem.
I am going to try to exchange the slim pen for a normal surface pen in hopes that fixes the problem.
Only have had the surface for 3 days.
Has using the normal surface pen worked to solve this issue and is there any other recommendations I should do?
If anyone has any other suggestions that would be great.
Thank you
