In Lightroom - "Edit In" requires two images to be selected to make menu options available should only be one. "Photomerge" menu options not available with one or 2 images selected. This is a software bug. Running windows 7. Have uninstalled and re-installed both Lightroom and Photoshop but it has not fixed the problem. Please advise. Not sure how to report this to Adobe.
I think, I know, this problem is specific to your computer.
I also use Win 7 and don't have this problem.
I suspect the first image you are selecting isn't really available, Missing, in some way.
For both HDR and Panorama to become available all you need is 2 images selected. Try trashing the preferences file which wouldn't be replaced with a reinstall as it is located in your Username folder.
You are correct. The issue appeared to be with one image that I had edited and then made a virtual copy so that I could edit in Nik. I have synchronised that folder of images and my menus have returned. However, I have lost the lightroom edits to other images that I made after the virtual copy of the earlier image. They were just quick edits so they are easy to re-do. I am reluctant to make a virtual copy again in case this happens again, although I might try later in the weekend to see if that was the actual cause of the problem.
Thank you for your assistance.
