Modification needed in scrollbar in flash 8 file

i am a newbie flash designer. a client has asked me to make modifications in a flash file used on his website. it is flash 8 actionscript. i am currently working on the same and would appreciate your help. the client has given me ‘proprietorytools.swf’ file which i decompiled using sothink decompiler 4.5 build 90120 to ‘~proprierarytools original.fla’. the xml folder resides in the same folder as ~proprierarytools original.fla. it contains proprierarytools.xml. you can download these files at

i discovered a problem - if you view ‘proprietorytools.swf’ - when you click on ‘aims’, you can see that the scrollbar works perfectly. when you click on advigil, you can see that the scrollbar is faulty. it starts lower than the other links scollbars and has no thumb. the entire text in the xml file is not displayed.

please help me to resolve this problem.

my additional questions are:
has the creator of the swf file use some unique scrollbar code or is this scrollbar provided in flash itself. in this case, i can read a tutorial to understand it better.
is it possible to copy the scrollbar code from the links where it works, to advigil, where it doesnt work
is this an easy bug to resolve or is it difficult?

i have given ‘scrollbar works.jpg’ and ‘scrollbar doesnt work.jpg’ to further explain my query.

please tell me if i have explained my problem properly or further clarifications are needed.
