QTR-Quadtone RIP

Hi
Quick Question. I am trying out QTR and like it so far.
However when I have  the 'scale media to fit' checked I get very strange behaviour.
My page size is being ignored and image is not being scaled. only half of it is being 
printed.

When 'scale media to fit' is unchecked QTR is working fine.


Is this just my install of QTR or dos QTR only work with photoshop 'scale to fit media' off?

Thanks 
Peter Miles
