When running Image Processor from Bridge via photoshop, any open files in Photoshop (that have been selected in Bridge for processing) will close after processing -including UNSAVED FILES. I have never had unsaved files close without prompt in Apple OS.
In 2020, I was advised to trash the PS image processor, which I have done. Issue persists.
Test procedure: Open new or existing files in PS. Make changes to files, but do not save. Select the test files from a folder in Bridge: Tools>Photoshop>Image processor> Make JPG copies of files.
The files will close after Image Processor tasks complete, and unsaved changes to the selected files will be lost.
We work in a large, high profile production studio, using Image Processor with hundreds of files daily. This is a major issue for us. This occurs in multiple iterations of PS & BR, with multiple (current) versions of Apple OS (not tested on PC's)
The same issue did occur using earlier, recent Photoshop WITHOUT Bridge, but that issue appears to be (mostly) resolved. (I was a beta tester for PS1.0, and a contiuous daily user since that time)
