Can you open an image file in the Image window?
Go to the Image window.
Go to File
then go to Open
and navigate to a file, then open it.
Does that work?
Don't worry. I don't blame you - holidays are worth enjoying. And, if you were away from the computer, then of course you couldn't work on it. Get to it - and get back to me - whenever convenient. Thank you for keeping me posted.
