I'm trying to create a new per pixel skin, but while the SkinStudio preview reflects the changes, applying the skin changes nothing - it always seems to use the UIS2 frames.
Also, I'm wondering if frame borders (left, right, bottom) are a necessary part of the skin. Ideally I'd like to skin the caption only and leave windows borderless, but I can't find the option to offset the caption such that it doesn't paint over the invisible borders.
