Scroll bar component problem

1

i am using text the scroll bar component in flash mx. my content is dynamically loaded from xml. there is a nested movie clip on the main timeline with 5 topics inside (5 textboxes, new on each frame). text loads and everything works perfect until i open a new movie in upper level (it is a form i share between different categories). once the form is closed i still can scroll the text inside the latest displayed text box but when i press the button to see another topic (another frame on my nested movie clip) it stops working, no scrolling, buttons (arrows) change their look like being disabled. however, content is still there, just cannot scroll it down neither up. any help, advice? what i tried was loading into target clip, and using static text (embedded in flash) with no luck.
