I've had this problem frequenly lately. Sometimes CR will open up multiple photos so I can patch process sometimes it won't. Currently I'm in a rut of CR won't open multiple files. I have to go through them one by one. It's quite frustrating. I have a PC with Windows 10 and my CR and PS are both up to date. How can I fix this?
Thank you in advance!
The first thing you can do is provide some detail on your problem:
1. Do you select multiple thumbnails in Bridge, right click on any one of them, and pick "Open in Camera Raw"?
2. Do you get an error message, or does only one image open up?
3. Is the filmstrip visible on the left side of Camera Raw?
Lots of people here that can help, but you've got to give us a reasonable amount of information. Also a screenshot or two might help.
