I've selected an image from the Interesting category of the Flickr stream as I normally have. However, when I try to adjust the values to create a custom value, it simply will not budge. All the rule options are available except for custom, which is blacked out. I can save a mood closest to the one I like and adjust the theme afterwards, but this defeats the purpose if I want to work within the values of the original photo.
As soon as you move one of the color markers on the image, the mood setting changes to Custom.
Yes, normally this is the case. My particular problem was that the color markers would not move.
