I uploaded 2 photos to the gallery, the 3rd I was trying to upload, even though showing done, simply never happened - after many attempts - but that is not why I am posting.

I right-clicked on one of my uploaded pic and went to properties (something I always do) and PC vanished instantly as did my internet connection. I re-connected, logged in again, tried again and the same happened. I tried one more time with the same result!

I find that quite strange - why would right-clicking and going to properties shut me down completely?
