So, Parallels 4.0 is out. I was told by Parallels Tech Support quiet a while ago that 4.0 would support Windows Vista Aero interface. So does 4.0 support Windows Vista Aero? Don't see any mention of it on the Parallels website, do notice that DirectX 9, DirectX Pixel Shader 2.0 and OpenGL 2.0 is supported in 4.0. I don't automatically assume that Aero will work.
