Hi,
Some apps locks only parts of the files, blocking access to all users if
you haven't activated oportunistic lockings (allow locking only part of
a file, not the whole file) You can find more info about it in
http://www.samba.org/samba/docs/man/Samba-HOWTO-Collection/locking.html#id2609918
I hope it works for you
Greets,
David> Hi.
