Recently my aero theme stopped working, and it is rather frustrating. It has been working for the past 5-6 months, and now it suddenly stops. There is something weird, though. Whenever i start up Torchlight 2, the aero theme starts working, with transparency and all. Whenever i restart the computer or change users, it goes back to the basic theme. There is certainly no reason why my aero theme shouldn't be working. Can anyone help?
