I have seen this before - I'm not sure where -
probably this very mailing list.  My understanding of
a deadlock is that two processes are vying for the the
same lock or set of locks on the same record at the
same time.  Usually filepro will just allow the first
process to create the lock(s), and the second will get
the "someone updating" message.  For whatever reason,
it sounds like your process thought that it should be
able to do it's locks, but so did another process.
