Thanks! Guess I'll go make some UIS2 frames!
Not sure about Vista as still using XP, for XP the UIS2 frames must always be done as they are used for MDI windows.
Yes in vista too, for example photoshop cs3 uses uis2 (cs4 no), so i make first per pixel frames and after i make uis2 because some programs uses these type of windows....and always the preview in my skin don't work
