Thanks! and Wow! for the fast response!
it's 5am for me now.. so there's no way I'm going to dare attempt 
working some more on my project except conceptually (I spent a good few 
weeks conceptualising about my project while the Football World Cup was 
on earlier in the summer :) but I'll take a look at it in the morning 
and let you know if I want to have your kids :)

but it looks as if I could add a hasMoreElements() to that class and 
kill two birds with one stone (or kill one project with one class ... :)

would improve man, but it would deteriorate the cat.
