I have an online test in Flash. It is basically working ok,
but it is not reliable 100% of the time. The movie has 6 sections,
the first 4 use quite a few audio files. I preload all of the audio
(external mcs) in the beginning of the movie, while the user is
reading an instruction page. I have a preloader to do this. Some
problems that are occurring:
Occasionally, the preloader stops at a percentage and will
not load any more. Doesn't seem to happen very often.
Sometimes, when the user gets to section 5 of 6, for example,
there are no images displayed. It has also frozen at the beginning
of other sections. Yet it works fine for 90% of the other people.
It's almost as if all of the data did not get preloaded correctly.
I am wondering why there is this inconsistent behavior with
the same movie? One thing is I do not 'unload' any of the mc's I
preload. As a general rule of thumb, should one be unloading mc's
as soon as they are no longer needed in the movie?
I decided to preload all of the audio files at the beginning
because once the test starts, I did not want the user to have to
wait to load data. Is this a bad idea? Perhaps I should be loading
at the start of each section? Would that make it play more
