Hi,
I'm having this 2 graphical problems that I don't know how/where to fix:

1)
My skin used to ahve a color gradient on that.. and I've teste somse other skins and they do have a gradient or an image there, how can I do it? I don't like it all white... But I can't find where to change that.

2)
The progress bar on skinstudio preview (inside skinstudio) looks nice and nor background border but in windows, with some operations wich has a scrollbar I get that background that seems like a border... I want to remove it, where/how can I do it?

Thanks.
