Jeff,

Arggh, that was it. I thought rebooting cleared the host cache since I 
remember reading that restarting NBU processes had the same effect. I 
guess not.

That's at least the third time this has bitten me, am starting to 
dislike this new feature somewhat. I even mentioned it in my original email!

Cheers
James
