What have you done for trouble-shooting so far?
Restoring Preferences after making sure all customized presets like Actions, Patterns, Brushes etc. have been saved might be a good starting point:
The problem was suddenly there.
In the library folder preferences CS5 deleted and reopened. No result.
Did you try restarting with cmd-ctrl-shift pressed?
Yes I did, no result unfortunately.
Can you still edit the Fileinfo in Bridge?
Thank you for your answer.
In bridge I can see the metadata.
But can you also edit it?
Or was the issue only about viewing it?
The thing is: Photoshop CS5 is pretty old, so I can only recommend the basic trouble-shooting routines but I can’t test because I don’t have it installed.
