Are not these questions rhetorical? I hope you are not expecting any answers.

Yes. Practise makes perfect,right? Or simply put, lots of hard work...

Sorry, no , you actually said this quote
'It would appear that you've got your
sprites (the buttons you're wanting to program) spanning across
multiple frames in the Score (I'd guess 28 frames) and that the code
you've attached to them is attached to only part of their span.
(...)
So the first thing to do would probably be to shorten the span of
frames your buttons occupy so they are down to just one frame.� unquote.
I do understand what you mean. It is not necessary to use a few frames
when one would suffice.
However, if I wanted a sound file to finish playing how do I do it?
I can�t use a frame script
on exitFrame me
go the frame
end
because it loops.
If I used a single frame, how could the speech finish so that the playhead
could move forward to the next frame?

Sorry, I never said you did, did I?
What is the purpose of using a timer in Director?
From the help file:
If multiple timers are required, you must create and manage your own.(�)
Typically, you use the ticks property to track time in this manner.
Is this the reason why timers should not be used ?

Could you explain further please?
What is the difference between endSprite and exitFrame?
Isn�t the end of the sprite also the end of a frame? That is , I believe it
is not possible to have a sprite in half a frame?
Is this how it should be written?
property pEndTicks
on enterFrame me
pEndTicks = the ticks + (4*60) -
end
on exitFrame me
if the ticks < pEndTicks then
go to the frame
end if
end
With regard to handlers, on page 79
'You write a handler with the purpose of grouping a related set of
programming instructions, which are meant to cause the computer to behave
in a certain way. You can almost think of handlers being to programming
what paragraphs are to writing.'
From this, I gather that handlers are an integral part of programming.
They normally begin with "on something" example "on MouseUp" and you can
place many of them together on a single script. Am I correct?
OnGetPropertyDescriptionList is a system handler. What does this mean? So
there are different types of handlers?
Would it be correct to say then that scripts are usually made up of handlers?
