I am no developer, and do not know why all of a sudden, when I make a snapshot I get the bar above the picture, with title etc. as if it was a Finder window. I am either on a Mac Air 11" late 2011, OS 10.8.5, or on a MacBook Pro 15" late 2013. I updated Skitch yesterday, and this has been happening on both computers since. Thanks for your help.
