Yes, you have to script, give you a reference;
function high (which2) {theobject = which2 highlighting = setInterval ( "highlightit (theobject)", 100)} function low (which2) {clearInterval (highlighting) which2.filters.alpha.opacity = 40} function highlightit (cur2) {if (Cur2.Filters.alpha.opacity <100) Cur2.Filters.alpha.Opacity = 13 else if (Window.Highlighting) ClearInterVal (Highlighting)}
script>
