Thanks for all the great input, hopefully we can get a better viewer.
Smooth, I am not satisfied with the overall viewer quality. For example the jumping lines and the "sparkles" or "twinkes" as I call them, especially on exterior shots. I did not do any sharpening at all on any of the images just for this test. As you can see many others are not satisfied as well. I contacted Support and they acknowledged the problem and said an updated viewer was due in December, but no viewer. If I've said once I've said it a hundred times, I love the program but not the viewer. Granted it did improve some on the last update but not enough for me to sell.
Masayuki, I think the buttons you refer to was because the action I chose was to have the right and left rotate buttons be previous and next scenes.
Now, as for the "Walk-through quality is not fixed yet" I don't understand what you are referring to and the "algorithm" part, my friend that just went over my head and I didn't even see it.

If you know the "secret" then everyday is a good day!
