Scrollbar component question

hey i tried to use uiscrollbar component on my movie but t screws my preloader, its only shows when its by half. i disabled export for action script and export on first frame so that’s not the problem. what should i do?

by the way as i cant and dont want to have the work of changing the component appearance i want to make my own scrollbar. nothing elaborated just a line and a face to drag the htmltext field’s text. anybody know a good tutorial?

thx for the help
