Hi,

hmmm that's strange because yes there was a bug, and it has been fixed and 
tested by the one who reported it. I also just checked again my tests and 
they're ok.
I could not reproduce your problem. Can you post the complete code? I'm 
missing the definition of End, I suspect something with "none".

Unfortunately I'm on the way to vacations so I don't know if I'll manage to 
debug as good as at home, it could take a little longer.

Cheers,
Christophe
