Thanks NikoJorj,
I must be doing something wrong. I made a preset in library mode (save to hard drive) I also checked save as original, checked standard sharping, ppi 360.
When I bring this file back into PS the size has changed as well as the ppi
Being new to Lr, I guess I'm not quite ready for this and need to take time to learn more about Lr and clime the learning curve.
So for now, its back to CS5 for sharping, as I need to move on with this project.
