Ha - at least I know it's not me going mad then :)

I'm living with GPT labels at the moment (and labels on the drive caddies) 
- if that doesn't work out (it's currently "bearable") I'll tap LSI for the 
'magic tools', and drop you an email if they give me a copy.

You're right though it is *incredibly annoying* (especially when you don't 
know it's doing it!).
