My father in law has done something to cause the video play screen, with a play arrow, to become a ghost image on his notebook. When at the home screen you can see the icons behind it and they work fine.
It looks like the image where you would click on the right arrow to play a video yet there is no video to play. He can't close the window to make it go away and restarting doesn't help. He lives in AZ. so once I get to him am going to have him try to restore to an earlier date. Computer is functional despite this ghost image. He can click on icons on his desktop behind the ghost and they work, he just has to read through them.
Then it's most likely a software bug. Get him to scan his machine for viruses. Use programs like malwarebytes, SUPERantispyware, free Kaspersky and AVG scanners along with the antivirus that should be installed on his machine already.
You don't have to use all those programs. They were just a few I was suggesting to you.
