Yep, Windows applications often create a temporary file then rename it.
This means permissions info is lost.

Have a look at the "map hidden", "map system" and "map archive" options
in the smb.conf man page.

If you turn all 3 off then you will find that you will start getting the other
x bits back.

Samba uses these execute bits to map these DOS attributes.
