Samba permission problem

[Shlomo Solomon]

I will only be able to play with the log tonight, but in the meantime,
I can answer that my Kwrite example was just that, an example. The same
problem with Open Office files. Also, no change if I close and re-open
the files (in both programs). The reason I'm using Samba is that this
is a mixed network with Linux and Windows machines.
