Apologies for the triple-post.

I use google-groups for reading c.l.py, but I know that some people reject 
messages from there due to the volume of spam, so on the odd occasion when I 
want to send something I fire up Outlook Express and send it from there. It 
seems to be misbehaving today.

Sorry about that.
