No argument on that - just HOW it is created and then displayed :)

That is the CURRENT state of play - but I am fairly certain that is was
not always the case?
No problems now following the rules, but *ARE* the same rules used in
legacy windows systems ?
Something else that has come up - does Microsoft actually flag a GUID
where it has created a host number rather than using the machine MAC
Address - Not a Firebird problem, but if the data is supplied from a
third party application (or pumped in from a MSSQL source) it would be
nice to know that we can use the host data to group source records - or
not :)
