With Novum the scrollbars are just a bitmap so SkinStudio is not needed. Open folder for Novum, find the scrollbar bitmaps. Will be ScrollbarThumbBtnVert.bmp and Scroll....Horz.bmp. Open them in graphics software. These are a 3 state image, normal, pressed and mouse over, recolor to what you want. Note: they use magic pink, 255,0 255,
for transparency, this must not be recolored or it will show up.
Note 2: changes to anything in a skin can only be for personal use.
