This is driving me nuts! Please help!

Question

I created an animation of scrollwork (from a png file) that
looks like it is being drawn realtime by using the erase a bit at a
time and then reverse the frames method, however at the end of this
animation I want the completed drawing to fade out. However
whenever I create a motion tween and set the image alpha to 0% at
the end frame it makes the png's previously transparent parts turn
solid white.
I did this:
Imported the png (which has transprent parts so my custom
background on the stage shows) to the stage-> Converted the png
to a symbol -> Erased a bit, inserted new keyframe, erased a
bit, inserted new keyframe..... till the whole thing was erased
-> Reversed the frames -> inserted new key frame and end
frame, put in motion tween -> changed scrollwork symbol alpha to
0% -> play animation: Works perfectly until it gets to the
motion tween at which point the transparent parts go white but the
visible parts fade out like it should leaving the stage white.
Can somebody please tell me how I can get it to not go white
and stay transparent while fading out! Any help is much
appreciated!! :)
