Thanks for the reply. I kept tweaking my values and finally was able to get Lightroom to make some adjustment and ended up with 90x120. It's still a bit cropped, but I can live with it. I can't tell you why it finally adjusted, but it did. As I have over 300 galleries to produce, I'm working to keep the process down to as few steps as possible! Have saved as a preset as well.
Thanks again!
