I use private datasessions,with optimistic buffered tables, set reprocess to 15 seconds.
My application running in 5 or 6 users lan, in the line command seek(,,,,,) return update conflit in cursor!

Change the buffering from 3 (Optimistic Row Buffering) to 5 (Optimistic Table Buffering).

Any command that moves the record pointer in row buffered tables (Like SEEK) does an implicit TABLEUPDATE().
