Hi Benjamin (@innerscript). Firstly, my apologies that you did not get the user experience you were hoping for from us and indeed thank you for the detailed report on what happened.
Certainly, some of the issues you mentioned should not be happening and I have reported them to the developers. A number of people had replied that Windows 8.1 is not as fully tested with the Tobii Software as Windows 10, so if there is any chance for you to upgrade, I would encourage you to try.
Again, thanks once more for reporting this behaviour and we will do our best to ensure our software meets your expectations of quality in the future.
