Hi Greg,

Thanks again for the feedback.

I'm just off for a week of camping and Tae Kwon-do, so I don't have  
time to
look into these now :-(

I'll postpone the alpha release until these are done, if any intrepid  
souls
would like to send a fix to address@hidden for my return a  
week on
Monday, I'll put the release out then :-)

Cheers,
        Gary.
