Flash CS3 scrollbar does not work in all frames

I am trying to learn to create a website from Flash CS3, because things get very complicated to update through HTML. I've got my site completed except for a few things, like the UIscrollbar. My documents is setup with Actionscript 2.0 with Flash version 9 as the publish settings. The big problem is that I got a scrollbar setup on a few frames. The first one is updates, so that won't be scrolling for awhile and the others are for long lists. However, not all of them have the scrollbar show up in the test movie, when the lists are long enough for scrolling. If you want to see the problem for yourself, I am including a download link for the FLA file. You can see the problem on frames 5 and 8. Can somebody tell me how I can fix this?
