Photo 1.7.0.284 on Windows 10 64
I had some trouble with yesterday's session and since that Photo always starts with Untitled recovered document.
I actually had a valid copy of the image so I just wanted to close the document but Cancel did not close it. (By the way, should not be the second button "No" or "Discard"?) I was forced to save it with a different name and then I was finally able to close Photo.
However the same scenario repeats every time I start Photo again and again...
