OnRollOver/Out animation

Question

I have assigned the onRollOver and onRollOut event handlers
for a movie clip to enact an alpha animation function on an
interval, and it works, but only once.

Nick is right, you need to clear the interval function.
Basically a setInterval keeps running until the interval-id
is cleared. So,
you would probably be best off using a variable that is in
the scope of the
mcEnterSite... for instance.
mcEnterSite.intervalId = 0;
mcEnterSite.onRollOver = function():Void {
clearInterval(mcEnterSite.intervalId);
mcEnterSite.intervalId = setInterval(fadeIn, 10);
mcEnterSite.onRollOut = function():Void {
clearInterval(mcEnterSite.intervalId);
mcEnterSite.intervalId = setInterval(fadeOut, 10);
function fadeIn():Void {
mcWelcome._alpha ++;
updateAfterEvent();
function fadeOut():Void {
mvWelcome._alpha --;
updateAfterEvent();
