Thanks. As it turns out, what I want to do can't be done. At least not in PS. The area that needs to be fixed has movement in the form of clouds moving across the sky. In order to get the proper colour/texture match, different source locations need to be used at different times. PS (not sure any editing app for that matter) can't handle that. Frames to Layers isn't available in the 64 bit version either. Switching back and forth can be done but it's inconvenient.
I may not understand exactly what the specifics are of what you are trying to do but the healing brush applied to that spot in each image via an action or droplet might be an option.
