Picture this in your mind,
a timeline 12 frames long
a mask layer 20x6 in size
a movie clip under the mask layer that contains 3 buttons
lined up next to each other, this mc is 20x6 in size
Starting Key Frame the default small size
2nd Key Frame the enlarged size
3rd Key Frame the default small size
Between the Key Frames Tweening occurs to grow and shrink the
Button Movie Clip
When the user mouses over the mc the mc then grows to 100x30
When the user mouses out of the mc the mc then shrinks to
MouseMove events and the mouse out trigger after the Mask and
the button mc grows and reaches the next key
Now the problem. frame
Cant interact with the buttons
After the mouse out mc's then shrinks back to the default
size but mouse over no longer functions.
So, my assumption is that it has to do with the key frames
and possibly the player interprets the key frames as new instances
even though each key frame i ensure that the name of the mask and
the button mc are on them they dont see them as the item from frame
1 in the timeline.
the first thing that comes to my mind is the on the 3rd key
frame you don't have the instance name of the button set.
I have had that issue where i do the timeline animation and
then go back and name my instances and forget one of them. Check
that, if not, I can try to duplicate the problem.
