The effect I want is this: as each new item in a list environment is produced, it shows up in the active color, and all the previous list items move into the inactive color (but stay visible). I don't want all list items to be shown in the inactive color when the slide first comes up, and one by one become active. I only want one active item at a time; all previous items inactive and visible; all subsequent items invisible. How can I do this? Thanks, Alasdair
