i can confirm this too. Its really annoying. I tried everything to get my built-in windows 10 screensaver to lock my screen and my computer to turn off the screen after 10 minutes (which worked since years before i installed the tobii software).
I have 2.16.5 installed as well
My windows = Windows 10 Pro 64-Bit (10.0 Build 18363)
Its definately a problem with the tobii software and has no relation to other drivers or products.
Please bring an update asap as my screens are not locked which is absolutely inacceptable in my situation (use it for work too) and i am used to have it lock automatically after one minute.
Also its not good for my displays/monitors that they do not turn off during the whole night. Also it costs power and is not enviromenent friendly and costs me money as well.
Please fix asap.
