I emailed TGTSoft today about StyleXP not working with my XP build when it said it would. Informed them that I had installed SP1 but that it hadn't been working even without it. Within 1 hr I had a email back from them and a new beta was posted at TGTSoft. I installed it and all is well with XP SP1 Beta 1063.
