The dreadful Scene Change and Preloader

Question

I've put alot of blood, sweat, and tears into building this
site and the simple parts are causing the most trouble.
Scene changes work (used to), I found early on that if I
moved the longest scene to the end, it did not conflict with the
other menu buttons. It seems like at random, or when the movie is
slow to load, the buttons go to the wrong scene and start playing
at random frames and the buttons will not react.
Preloader works (on one scene), when i move the same eact
code to another scene and just change the instances and scene
information, I only get a blank screen when the movie is loading,
and then to top it off, it will redirect to another scene in an odd
frame. I have tried a number of diferent codes to make the
preloader work, all of the standard "stay on this frame until the
rest load and then play" codes.
I think these two problems are related and I was searching
for informaiton on ROOT and GLOBAL because I don't really
understand them. You can see some of my flash site at
www.danieljkessler.com I think the problem isn't the way I am
coding but something I am missing that is conflicting with scene
changes. Again, the navigation seems to work fine in the actual
movie file, but when its online or Previewed, it has these nasty
problems.
I am willing to pay a small fee to have them fixed or I will
fix them myself if someone can enlighten me as to what causes these
problems.

Answer 1

i found out that you cant put a preloader on each scene, only
one time. So that was the problem. Took me a long time to figure
out the preloader script to only load partially, so I'll post that
here incase someone else has the same problems. Also, for that
person, you want to create multiple swf files and load them into
the file from the external location. That way you can have a
preloader for each scene. A note is to try to avoid scene changes
and work within one timeline, and also that scenes load top to
bottom unless you change the publishing setting, so if you are only
partially loading your movie and find some of the buttons to link
to the scene immediately, rearranging the scene download order by
dragging the scenes in the scene window in order can help to
correct this.
Second, the problems with the scene buttons not working when
the file was loading is because they are linking to scenes that
have not loaded yet. The preloader helps to fix this. Using the
frame name instead of hte scene and frame number usually works but
I think flash like consistency. If I use the same button in
difference instances, I had to use the same format for the
onRelease to work.
I have to say, flash is powerful but its also a huge pain in
the ***. Don't fool yourself, CS3 is not all mighty. I can't
emphasize enough how easy the hard things were to do and hard the
easy things were to do. Flash design is fun, but flash scripting is
real sorcery.
Thanks for all of your quick and helpful replies kglad,
especially during the holidays. My site can be viewed at
www.danieljkessler.com , I still have to do the chinese version,
but I plan using the same file and changing and redoing some of the
buttons with english. God help me.
