Since Microsoft does not have a 2016 photo gallery with editing features I finally got 2012 photo gallery downloaded (thru 2012 windows essentials) on my 2016 laptop with Windows 10.  When opening the photos thru Files Explorer I have no problem getting a full view of each single photo even when scrolling through them.  When I open up 2012 photo gallery, then a file and photo, to view in full display the upper left hand corner of each one has a small square area that is plank.  FYI, since downloading some photos I have not played with any of the editing options.  It also doesn't matter whether the photos were downloaded by various cell phone or cameras so it can't be their settings.  Even when I deleted the software and downloaded it again it is does the same thing.  To make it even stranger it only does it when I open an individual photo or slowly move to the next frame.  If I speed it up the forwarding movement (by click real fast... 2-4 times)  then it allows the ending photo to show in full view! 

Has anybody experience the problem?
