Scrollpane Component Styles

Hi, I’m trying to change the style (color & images) of a scrollpane component using AS2 in CS3.

I’ve googled it a number of times, finding various possible solutions but none work. When I try to double click the instance of the component on the stage, it doesn’t open up as other symbols/movie clips do.

Also, I found a solution that involves writing some AS but I’m unsure how to go about doing this.

Any help?

Thanks!
