Make sure you have an 8.1 shellstyle in your theme folder. Maybe that's your problem.
BTW that light gray line in your TBUI scrollbar picture means that you still have some of that color in your image at
Taskbar & System Tray > TaskBand > Aero > TaskBandExtendedUI > Horizontal > Thumbnails & Controls > ScrollBar > Main Image
Check it to make sure.
I'll check it.
Btw. Is it possible to force 92dpi on ? I'd like to use higher caption bar height, but it automatically swithes to 192dpi setting.
Window control glyphs are now way too far away from each other.
Edit: Yup, that was it. I only edited glyphs not the main image.
