Photo app hangs
My photo app hangs often when I try click on a thumbnail of an older photo. Most (not all) photos imported into older versions of Photo have a little ? or a little disk symbol in the upper right corner of its thumbnail. If I click on a thumbnail with a disk symbol, I get a message: "Missing File. Photos with unavailable original files cannot be opened". I have the option to "Find Original" or "Cancel". Fine, both buttons work.
BUT, If i click on a thumbnail with a ?, more than half the time, I just get a blurry, larger thumbnail and no message about a missing file. The only thing I can do is hit the back button, and then I get the spinning ball of death, and I have to force quite the program.
This happens A LOT, and it is a pain, and time consuming. What can I do to fix it? Thanks for your help. I have the latest OS and programs.
