I've been enjoying not using a small portion of desktop for about six months now, and my desktop has been properly corralled until a couple of days ago, when my company updated Windows 10 to Version 1803 (OS Build 17134.2026). Since then, it's as if the Coral is just a picture on my desktop. It still behaves itself (i.e. docks, resizes) but programmes don't recognise its authority.
