Bruce,

Thanks - I've already implemented a tracking table method with a wrapper to RLOCK and UNLOCK - but I am still interested in finding out how the OS handles lock as it would potentially enable implicit and explicit locks to be monitored

Cheers

However, I have done this sort of thing in vfp in a home-made way - when a user locks a record, you can write username and PK (and table if necessary) to a tracking-table on server, not difficult to do.
