Elias, thanks for your extensive reply. I appreciate it, but I'm still having
trouble.

Thanks for "Preview" etc.


Okay, I've gone to 10 fps for clarity of discussion.

I cannot do this in one step for some reason (perhaps you have a PC), I have
to scroll the timeline out to about 595 first, then I select that frame and hit
F5, then scroll out to 1190, then select and hit F5, then scroll out to 1300,
then select and hit F5.

It looks like the sound ends at the right edge of frame 1266.

If I try to drag the end of the sound back to 1266, it looks like a new copy
has been added. If I UNDO twice, then the "missing" waveform is not refreshed
(erased), or is still set as a copy. What a pain.... I actually have to go to
a different app, then come back to Flash to see the correct waveform...

Is there a way to drag the end of the sound back to frame 1266 ?

Otherwise, how do I now shorten the sound back to 1266 ?

"...allows you to scrub the timeline..." - I don't hear anything... Is there
a way to hear the audio?
