Help with Lagging Frames

Hi,

First I want to start off with Thanking everyone who helps out. It means a lot to me!!

Second, here is my issue.

I am creating a training course in flash. I have 9 different .fla files ( the reason for this is because if it was all put in one, then the file size would be too big for any computer to handle), which go in this order:

Intro - just a brief intro for the course
Section 1 - Each section consists of a different topic that has streaming audio for the narrator. At the end of the topic (each about 15 - 20 mins long) there is a short pre-test that consists of 4-5 questions. Each section at the end of the pre-test has a button that links it to the next section which is a different .fla file.
Section 2
Section3
Section4
Section 5
Section6
Section 7
Final - 20 multiple choice questions related to the above topics.

Now, the problem: When I start viewing any file in Mozilla or IE the first one runs through the topics and narration fine, then the test works fine but then once you click the button to bring you to the next section (which is a new .fla file) the frames seem to stand still while the narration just keeps on talking. Then once the narration is finished and the flash file itself keeps running until it is at the ending, the pre-test comes up, and the pre-test will not work. It does not matter which multiple choice answer you pick, it will not advance to the next question.

When you run each of the publish .fla’s themselves, they working flawlessly, how ever altogether they do not work so well!

Any ideas?? Thanks again in advance!!
