Image button states challenges
I'm trying to create buttons from images with three states: Normal, Hover and Visited. Each "button" is a shape with an image. I want the image to grey out in the visited state. It looks like it is greyed out in the edit states panel, but doesn't grey out during preview.
In the attached .story file, the first slide does what I want, but slides 2 and 3 do not. The visited state does not grey out the images, though it does toggle to Visited because the outer circle border changes.
I'm stymied. Any ideas?
