I sometimes get something like B when I start with A and then I ctrl+drag up in the wrong place :/
Personally I only ever get A, because I use block diagram cleanup, because life is too short. People have a semi-constant level of irritation with me and my code as a result, but
Been running it for a week now on my development PC and seem OK with LabVIEW.
The update from Win 7 to Win 10 was problem free for me, but did take a long time.
My only real issues so far is with a Cisco VPN Client, that no longer works at all so I need to use a Windows 7 PC still to get access to my factory located test systems.
