Button handler never runs

Question

I currently have a new button that seems okay (over behavior
shows correctly), but the .onRelease handler never hits a
breakpoint on the first statement. I tried the following experiment
on an old working button and I can't understand what I observed.
The working button is defined on the whole timeline, i.e., it
appears on frame 1 in a layer that has keyframes only on frame 1
and the last frame. The button handler is in Active Script on frame
1 in a separate actions layer. The script applies for the whole
timeline too. Now if I take frame 1 of the buttons layer and move
it to frame 5 so the button does not appear until frame 5, geez,
the button handler never runs. What is happening?
I tried the above experiment cuz the new button I can't get
to work does not appear at frame 1, even though its handler is in
that script that is on frame 1 (like the documentation tells you to
do - gather up all your code into a single program on frame 1 in an
actions layer.) However, making this new button start on frame 1
(by moving its starting frame back to 1) did not make it work.
Another property of my non-working button is that it is in a
layer folder. Moving this layer out of the folder made it work. Is
there some restriction that buttons can't be in a layer folder -
I'm using Action Script 2?

Answer 1

If the button script is not on a keyframe in frame 5, it is
"not there".
Enter an empty keyframe in frame 5, put the button script on
that
keyframe. Now the button (in frame 5) should work, too, if
you did not
mess anything else up. :)
Just because the script from frame 1 is shown in the AS
window when you
click somewhere in the timeline after frame 1, does not mean
that it
works the way you think it should.
