Scrollpane border skinning

Hi,

I’m having a real ball-ache trying to skin a scrollpane component (and all components in general in MX2004 - I just can’t get to grips with the new skinning system)

I basically just want to be able to see the scollbar, but I want the border to be invisible (or the same colour as the movie background).

So basically I’m trying to make a borderless scrollpane via skinning

Is there any easy way to do this?

Many thanks in advance
