Thank you for kind reply.
I usally use tap window mode. I'm sure there is no minimized widow.
The problem is, document what "Photoshop ask to save or not" doesn't exist.
I've already save and closed all documents, and there is no document opened on photoshop.
But photoshop ask me save or not for non exist document.
If I try to save, Photoshop shows error, "there is no document for save".
Anyway, Thank again.
it'll be useful "check the Apply all"
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:
