I worked on this problem yesterday morning.  I tried several
combinations of lock options (oplocks, locking, veto oplock files ...,
fake oplocks, kernel oplocks) with no success.  The only option that
even altered the way the app acts was the share modes option.  With that
on (default) one one machine at a time can launch the app.  With that
option off any number of machines can launch the app but they all crash
as soon as you try to actually do anything useful - plus I'm pretty sure
that would be a great recipe for data corruption were I to leave it that
way anyway.

I've also posted on this problem on samaba list.  The only response I
got was to try oplocks which I've already done.

Does anyone have any ideas - I'll try anything!
