Sickpuppy....you are quite wrong.
Currently, the majority of 'XP'-specific WB skins are intended to emulate and improve on the style of the default XP skin, however, I for one am running my own skin in XP...[BlindJAFO-X] which has absolutely no similarity with the default XP what-so-ever, in fact, all the controls are at top-left....something I don't believe this new 'proggy' can achieve.
If you were to skin for WindowBlinds, you would soon see its potential for diverse style and layout. Essentially, the sky is the limit, and definitely far more adaptable than a boring old colour change or bitmap swap....
