Yes I did that and the layers switched positions.

with setting the projection to the lat/long layers, they are not found

Thanks for the good reference. The reason why I got into this situation 
was because I am four steps removed from the data provider. I only 
managed to get the information that you already know and I was hoping 
the information was correct. The other problem was that I was not sure 
how to identify the issues, confidently. If not I will definitely push 
for more information.

Cheers and thanks again,
Chris
