Edit Photos In Acorn 7
I am trying to edit my photos that are in my Photo App in Acorn. Because I have so many images, I have created a New Library on my 4 Tb external hard drive. I then, in the Photo App, select the image to edit and open it in my Photo App. Once open I click Edit. In the Edit window I select Edit in the Acorn Extension. I then Make the edit I need to and save and close the Acorn window. Then I open the Photo App window where I see the Edit I made in Acorn. I click "Done" and I am faced with this window (see image). Any one know what is going wrong? I can do this if the Library is on my Desktop Hard Drive but NOT the External Hard Drive.
