impossible de décocher "enregistrer en temps que copie"

[derrek5C9C]

Hello,
when I want to save and overwrite my file for example "file01.JPG" I cannot uncheck "save as copy" and I automatically have a 2nd file "file01-copier.jpg" which is created
how can I uncheck the box?

Have you tried resetting the preferences?
