How did you do that? In control panel > admin tools > scheduled tasks, there is an Aero Glass activity, edit and correct the path to where the aerohost.exe is, then stop and restart the task. It'll starts With some colour colorization, the theme appears too flat (with other colours doesn't happen) expecially on inactive windows.. there's a workaround for that? (maybe I missed to set a parameter) It's possible to have perfect round corner also using a theme? (as Vista did) I'll continue to test (I should say "use" instead xD) it, however it's pretty stable and nice; thanks again big muscle =) RE-EDIT: Disabling "theme signature bypass", the inactive windows are not flat anymore =D
