Scrollbar color

[jbv at souslelogo.com]

Hi list,

Is there a possibility to set a custom color to a regular
scrollbar ? I guess the answer is no, since I haven't
found anything in the doc. I also guess that the only
solution is to build a custom scrollbar.
My problem is that the scrollbar looks ok on Mac, but
on Windows it's 100% black...
I tried "set the backgroundcolor of scrollbar x to grey",
I didn't get any error but nothing changed.
