Button Rollover Fade Out Question

[flash555]

How can i fade a button out after a rollover. It seems as easy as assigning a mouse event to a MOVIECLIP but I can't seem to assign a mouse event to a clip. An example of this would be http://www.mtv.com near the logo. The button isn't going to link to anything, i just want the event.

In the Rollover frame of your button, select all
(after having put a keyframe in all the layer of
the column of course) and convert it to a movie
clip, then in the movie clip, make the anim you
want (the fading one for example).

For fading, there are several ways to do it,
depends of what the buttons look like, but the
way that always works: convert (in the movie clip)
all the things together in a graphic symbol, then
in the last frame of the anim, make a keyframe,
then select the symbol, right-click and go to Properties>>Color
Effect and choose Alpha, then put it at 0. Then go
in any frame between the first and the last in the timeline,
then click Properties, then go to Tweening,
then you choose Motion (and don't forget the stop
in the last frame of the movie clip if you don't want
the anim to loop.

Hope it helped.
