When people post photos on threads and I open them up, I can't get them off the screen. I press the x in the top right corner to no avail. I can spend five minutes trying to get rid of the photo off the screen and often have to give up 
and come back to it the next day and try again. Eventually the photo goes off the screen.
This has happened so often over the past few weeks that I hate opening up photos in case I get locked out again.
Has anyone else had this problem?
