Alas sorry for the late reply.

The box died just after I made that post and I've only just got it back up 
and running.

At the moment its still with its default config - I'm just waiting for it to 
calm down a little before I start changing things again. Once I've changed 
it I'll let you know what happens & how it behaves.


Cheers
