Multiple people are experiencing this problem with freshly installed/up-to-date/brand new Surface books. Also my colleague uses a standard mouse and I use a gaming mouse (which has all the latest drivers etc.). If you folks read through this thread you can see we have tried all the 'standard reply'-stuff already and more. We even have a good suspicion of where the problem might be by eliminating many factors.
The hardest part in forums like these is convincing 'support' that it's not a standard issue thing and probably something beyond their reach. That's where threads like these usually die because support will not acknowledge that and take further action.
Well MS likely does not patrol these threads. The correct way to submit problems is via the Feedback hub.
