[Samba] write permissions with drag and drop

[Hervé Hénoch]

Hello

I've configured the following share in smb.conf :

[wp]
    path=/backup0/wp
    browseable = yes
    valid users = admin
    writable = no
    read only = yes
    create mask = 0400
    directory mask = 0400
    printable = no

Logged in "admin" user, when I run a ".bat" script I can't copy any file 
in this share. This is ok.
But  I can copy a file in this share by draging it with Windows explorer 
....

How can I prevent this ?

smbd -V give : Version 3.5.6

Regards
