Thanks Dan & timinus,
Finally something that worked on my Cube Mix Plus – I was just about ready to throw the keyboard across the room in frustration!
I have found a strange thing though. With the registry key added to disable WIN+D (as via timinus’s link above), I’m finding that a down-swipe from the top edge of the touchpad is sending the letter ‘d’ to the system. For example, when I have MS Word or Notepad open, a down-swipe can trigger the letter ‘d’ to be input at the cursor location. So it’s much better than the global minimise that was happening before, but still a bit frustrating when working on a document. Any thoughts?…
