Hi Darren,
unfortunately I was able to reproduce this behavior in each and every newly created VI in LV2013 x64 I created since I found out about it. My first guess actually was a corrupted control, so I tried it with another scalar control next to the "offending" one, which, I seem to remember, changed to an array as I expected. After that I tried to figure out what was causing the trouble resulting in the screenshots I posted. In time I decided to try and restart LabVIEW in the hope something got messed up, and yes, there came a window about some DWARN messages after exiting LabVIEW, which I, if truth be told, receive from time to time - I stopped worrying about those.
But after I restarted LabVIEW, NO control whatsoever did me the favour of turning into an array ever since. Not even when I replaced the possibly messed up copies in my LV2013 x64-QD-folder with the original one from this very thread.
Again, I repeat - I had been working with this great shortcut since its release, on this very same computer (and on others). It is highly unlikely that I would have never, in all this time, used it for turning a control into an array in x64 before some days ago, when I became aware of this oddity.
This being said, I really think it must be something about my LV installation that's causing it and most likely nothing about the programming of the shortcut or indeed LabVIEW itself.
