tweening soundproperties only working when init method in same frame

[GoogleCodeExporter]

using the version "tweener_1_33_74_as2.zip" on flash cs3 on mac (10.5.7) i
recently discovered a strange behavior.

my first attempt of tweening the volume of a sound object via tweener ->
did NOT work
then i checked if my sound object code worked at all (playback and volume
set without tweener)-> did work
then i checked the sound example from tweener -> worked
then i copied the exact source code from the example to my project -> did
NOT work

finally i moved the import of the tweener classes and soundproperties init
method call to the same frame as the Tweener.addTween call -> finally it
worked!
