I have tried merging several different panos, typically 3 at a time from Nikon D7100 raw nefs, and the preview looks fine. When I click on merge the progress bar goes to about 54% and then locks up the computer. I have to get to task mgr. to get the machine working again. The HDR merges work just fine.
I have a Win 7, I-7, 8g ram machine. I can get panos to work in PS CC with tiff or jpg files. It would be nice to do it all in LR. Any ideas?
Thanks,
Mike
