Hello! I'm using Windows 7 BETA I'm having a bit of trouble here. After installing Realtek HD Audio Driver and Live Mesh Client transparency suddenly turned off and window's color became black. All the windows and the taskbar look like this: trans1.jpg - Windows Live I tried restarting the Desktop Composition Service but it does not work. I also deactivated and activated again Aero, but that didn't fix the problem either. Strange thing is that in Windows Color and Appearance settings Enable transparency is checked. And when I try to unckeck it and check it again transparency activates for a while, but then suddenly dissappears on opening a random system window like control panel or even taskbar properties. trans2.jpg - Windows Live Here is what it should look like: trans3.jpg - Windows Live Does someone know how to fix this?
