Could the preview button just bring up a simple image or animated clip, without referencing the actual windows from the user's session? Could be a screenshot or short clip, or something more diagrammatic like the Panel Settings popup. I would think that people just need to see what is meant by "Cover Switch" or "Flip Switch" to know if they want to try it out. -- You are receiving this mail because: You are watching all bug changes.
