Maybe Windows 8.1 has been updated. I tried close button and Alt+F4 with a
few Apps and now Alt+F4 closes effectively the App.

I saw this on a mailing list...

"I happened to be looking at Process Explorer just after I had closed
the Flipboard App with the upper right corner X, and I saw that its
state was 'suspended'.

"I killed it, and started it up again. This time I used alt-F4. When I
checked Process Explorer, there was no sign of Flipboard.

"So, what does this signify???"
