Like this: There themes out there to make it look like OS X. BigMuscle only does Aero glass With minor tweak of his code he can archive it easly. Why not having this type translucent into windows i don't understand why you're negative. Aero glass is customizable after all, he could add a param to enable it if the user want. Any how this is almost "flat" style of Aero Glass of Windows 7 but with another blur kind ... What you're saying "BigMuscle" ? Thank you
