I have a Flash animation with a series of text graphics and photos fading in
and out (at different rates) by changing the Alpha values for the text and
graphics. A streaming MP3 file is playing in the background. Halfway through my
animation (about 2 minutes), I begin to see "ghosts" of other already-faded and
yet-to-appear text blocks against my pictures, printed in the color of the
background of the Flash animation. Anyone have any ideas what might be causing
this, and what I could do to fix it?

Its bugs in the player

There are limits to how many transparent/faded objects can be on screen
overlapping at once. You can get some nasty ghosts and glitches.

Do not have things left on stage faded out to alpha=0 .. instead remove them
until they are needed and remove them again when finished (or if you are
doing your fading in script, set _visible=false to make them disappear)

I read about alpha problems in this forum and in ?Flash to the Core? by Joshua
Davis that describes them as ?jitter? or ?jags?. He mentioned that it was a
common problem with imported images when tweening. His solution was setting
the alpha level to 99 instead of 100.

I actually found a solution while I was experimenting. Changing the tint, and
setting the tint color to the stage background color, can achieve the same
"fade" effect as the alpha. Since alpha is more CPU-intensive, definitely use
the tint method when possible, and when the object isn't overlapping anything
else that you'd want to show.

I tried removing them by creating keyframes before and after my fade, and then
moving them off of the stage at those keyframes. I recall it not working...do
you suggest any other ways to remove the objects?
