All updates have been completed. I am using CS6 version 7.3 Raw Editor, PC based, Radeon graphics card, 16 GB RAM. Weird goings on. I shot five sets of 5 images, +1, +2, neutral, -1, -2. These were all shot sequentually. In two of the sets, the program goes directly to the HDR preview and I do my 32bit edit thing. In three of the sets, no matter what I do, or how I do it, when it gets to where it should open, it disappears. Poof, it's outta there! Adobe is clueless. I spent the better part of two hours while three of their techs worked within my computer via a share program. They are still baffled and supposedly will get back to me tomorrow (3/7/03. In the meantime, and since I don't have great faith in them, does anyone else here have any experience with this type of anomoly and perhaps a solution?
