As a skinner since WB4, things have changed a lot with skinning. With the advent of Vista, and then Windows 7, skinning became more time-consuming. It takes me about 2 weeks to skin XP, and another three to four weeks to skin Windows 7. I am not complaining...it is just that there is so much more to skinning Windows 7, and most of the images used in XP cannot be used in 7, thus, in essence, I am making two complete blinds.
