@RustyMG yes, in fact, I did read the documentation. Although what I was experiencing involved nothing that I read, hence my question. Maybe hold back on the attitude, people don't ask questions if they know the answers....
Anyway, I thought I downloaded the 0.78 set, but clearly not. Do you have a link of the best place to get them from? (and yes I will be googling it again in the mean time)
Cheers
