We need to know how OpenOffice on Linux does the exclusion of "another
user has this file open" and how this interacts with a Windows user.
Windows apps usually use "share modes" to provide exclusive access,
POSIX doesn't have this so it uses byte range locks to do the same thing.
Until we know how OO on Linux does this it's hard to speculate
as to exactly what is wrong. This is important enough to Novell
(who pay my wages :-) that I'll look into this - it's something
we just solved for simultaneous access from NetWare and CIFS from
Windows clients.
