When I want to exit a photo, I just click outside pic where the post area is. It takes too long for me to find the X when it way over the right hand side of screen. And that's one of the problems I was having: No X just the message: "Import to databaseimage 2of 5nextpreviousclose" and no "image 12 of 15" with arrows to move thru the pics.
Above was just observations while reading 2 different posts.
Since I got back on again, I haven't seen it happen again so far.
