wine users - Mar 2010 - Wine on Mac OS X: Open MS Access DB on network share (Samba)

Hi,

I am using wine 1.1.35 on Mac OS 10.6.2.

I have trouble getting an application to run that uses an MS Access database.  

The access files are on my host machine and I used winecfg to give the folder a
drive name inside wine.  I configured the application to access this drive and
it works fine.

However, if I use winecfg to point the drive letter to a samba network share
mounted on the host machine, it refuses to be opened, saying: "The database
has been placed in a state by an unknown user that prevents it from being opened
or locked".

In both cases, the contents of the folder are identical (including permissions).
Yet, if the folder is a network share it won't work.

The problem appears to be similar to
http://forum.winehq.org/viewtopic.php?p=40893 and I followed the advice posted
there.  One thing I didn't manage to do was to chmod a+rwx the samba share.

Any help?
