samba - Feb 2010 - Samba 3.4.5 & Offline Folders & windows 7 (again ..)

Hi!

We tested the offline folder synchronisation with windows 7 and Samba 
3.4.5 the
last days.

We constantly facing the problem if you change a file (e.g. a Excel 
spreadsheet)
-  does not matter if offline or online -
and you are start the offline sync in win7 then it claims about a 
synchronisation problem
with that file.
Win7 states that both sides have changed.
We don't face that problem if the share is located on a win2003 server - 
but I don't really
know where to start debugging here.

Does this sound familiar to anyone here or are my share definitions wrong?
